A fresh start

As many of you know, be it from the news or from what I occasionally post on Twitter, the situation in my home country, Venezuela, is dire. Shortages of food and basic goods, lack of medicine, rationed water and electricity, wages that buy but a fraction of what you need, rampant crime and rocketing inflation have thrust Venezuela into a chaotic spiral that keeps getting worse every day. I had felt the pull of this hectic whirlpool for a while now; where I lived, an 8-story building right near a subway station, only had running water from Sunday to Tuesday. Water service the remaining days was active 45 minutes in the early morning and another 45 minutes at night. I saw my salary  (as a researcher and as a college teacher) dissolve like salt in water. Even if I had money, food shortages prevented me from being able to buy basic things like flour, sugar, toilet paper, soap and other basic goods. New phones, cameras or computers were out of the question, since inflation meant that to buy them I’d have to save up for years without spending a dime.

Still I pushed forward, despite the adversities. For my area of interest, urban biodiversity (particularly insects), Caracas is an incredible place. Over 200 species of insects lived in my building’s garden, a small patch of grass with a few groups of flowers. I recorded over 50 species of birds from my window. Sloths were a common sight, as were geckos, bats and myriad other animals. Interesting bugs to photograph were but a few minutes away. But despite this, the situation was catching up to me, and I reached my tipping point in January.

A bit of backstory: I had already decided to drop out of grad school in early 2016, although “I was forced to by the circumstances” would be a better phrasing. When I started in 2012, my plan for my MSc thesis was to see which insect genera (species if possible) were present in the Caracas Botanical Garden, their distribution and density fluctuations between the rainy and the dry seasons. After 7 months of field work, being mugged twice and seeing another robbery, I decided that a thesis wasn’t worth risking my life, so I sadly abandoned that project. After a small bout of depression (it was a project I had wanted to do since undergrad), I put together another project, on campus, comparing pollination systems between the native forest and the urbanized area, since I wanted to see if there was competition between different species (particularly bees) in the same environments, or simply different species in each area. The main question was how urban landscapes shape and change the structure of pollinator systems when compared to native forests. All was going well, until roughly three weeks before starting field work, when a crime wave hit campus (11 robberies in two weeks) and access to the forest was suspended. This meant I had lost over 2 years in projects I couldn’t finish, and I had no more time left to try again before my graduation deadline. So I had to drop out.

I kept teaching and doing some freelance work the rest of that year. I barely made ends meet (teachers in Venezuela are woefully underpaid, and freelance work is volatile), and each week was an odyssey to find even the most basic items. I eventually gave up eating bread (since flour shortages meant that lines for buying bread were roughly two hours long), coffee was a rare thing to find, meat prices skyrocketed, and by the December I was eating, on average, one large meal and one snack a day.

Fast forward to January 2017. While going down the stairs to a subway station, two men approached me, and one pressed a knife against my back and told me not to move while the other one searched me for my phone. He pressed several times, threatening to kill me if I moved, giving me some pretty deep cuts. When he briefly looked away, I managed to elbow him in the face, push the other one down the stairs, and run away (I’m still not sure how I did that, since my fighting experience consists entirely of imitating the Power Rangers as a kid). Bloodied and paranoid, but still alive and “well”, I decided that while I loved my country, it wasn’t a place where I wanted to live anymore. My adult life was being spent surviving instead of living; hours spent on looking for food, having a self-imposed curfew of 6-7 pm because afterwards the likelihood of getting mugged (or worse) increased greatly, doing financial magic and living on less than 10 dollars a month, having to abandon grad school because I might get killed during field work… the list went on and on.

I dedicated every waking hour to get everything ready for my departure, with Chile as a destination. It had been the first choice for a while (great grad schools, stable economy, same language, lots of endemic wildlife, friends lived there), but I hadn’t reached my tipping point before January. It was a hectic time; moving out, selling what I could to have a bit of money for the trip, and fitting my entire life into just two suitcases, 20 Kg each. Everything came together rather quickly, thankfully, but given the situation the country was in, I had no idea if I would actually be able to reach the airport or leave the country, so I refrained from “going public” with the info until I was sure.

After much tension and anxiety, I landed in Santiago on April 11th. I was greeted by childhood friends who opened up their home to me and took me in, and I will always be grateful for everything they’ve done and are currently doing for me. My next step is finding a steady job, and then hopefully starting my PhD next year.

This past month has been a cornucopia of emotions. Happiness, enthusiasm, fear, anxiety, restlessness, nostalgia, homesickness, sadness, helplessness and at least a dozen more. I left everything behind to start my life over from scratch in a foreign place I had never visited, and that is terrifying. I left a career, friends, family, a relationship, my own place and lots of other things. I’m incredibly fortunate, though, because I’ve had a LOT of support from many different people, and I couldn’t have done this without them.

So here I am now, in another country, filled with hope of a new life while catching glimpses of everyday horror life in Venezuela through text messages or tweets. Midnight attacks by the National Guard on my mom’s apartment complex; friends having to sleep in the hallways because government-backed armed paramilitary groups (the colectivos) firing guns at buildings; having tear gas thrown at friends and family who are at peaceful protests; hearing voice notes from friends (freelance journalists) saying “I turned in an article that wasn’t too good, because I had to write it while the National Guard was firing tear gas canisters at my building and I was focusing more on breathing than on writing”; learning that, on average, one person a day gets killed at the protests (be it from gunshot wounds or tear gas canisters to the chest) or almost getting killed by being run over by a National Guard in an armored vehicle. Each passing day in Venezuela reminds me more and more of 1984 or Zlata’s Diary

So yes, this is a fresh start for me. It’s scary, but the prospect of actually having a life (instead of just surviving) is uplifting. And rest assured, there will be lots of pictures of Chilean bugs from now on.

NOTE: As I was writing this yesterday, I found out (by seeing a picture on Twitter) that a dear friend and colleague, Diego Arellano, was the latest casualty in the protests in Venezuela. With him, the tally is 43 dead in 40 days. He was murdered by a bullet to the chest. Diego was an excellent person, a great herpetologist, and firmly believed that Venezuela deserves better than what it’s currently going through. He is missed by everyone who knew him.

I have no clue what happened here

Last weekend I went with on a field trip to Guáquira Ecological Station in Yaracuy, Venezuela. During a walk to one of our field sites we passed a group of plants in the family Musaceae, and a small protrusion caught my eye. On the side of the leaf stems I saw a katydid in the subfamily Conocephalinae, tribe Copiphorini staying very still. As I got closer, I could see that it was dead. What was interesting is that it died while, apparently, laying eggs:

Laying eggs?

Laying eggs?

But there was something that didn’t quite add up. Upon closer inspection, the insect was fixed to the side of the stem only by the ovipositor, and there were no eggs to be found.

The legs were awkwardly folded underneath, it looked faded and it was in a conspicuous position; it had many signs of having been infected with a parasitic fungus, except there were no spores, fungus body or anything that looked like fungus. Very odd indeed. Then I looked at the other side, and things got stranger:

Parasitoid exit hole

Parasitoid exit hole

That looks like a parasitoid exit hole, which makes little sense, at least from what I’ve seen in the field. I usually see these exit holes in eggs, larvae or pupae, not adults, but it’s possible. There are tangle-veined flies (Nemestrinidae) that have been reared from katydids, as well as some tachinids like Homotrixa alleni, but nemestrinids and most tachinids are larger than this exit hole. So what could this be? A random occurrence? A parasitoid that modifies the host’s behavior and makes it die while making an attempt at laying eggs? A katydid that had a parasitoid inside it and then got infected with a fungus that modified its behavior, but the parasitoid ate the katydid from the inside out before the fungus could? I have no clue; all I know is that I’ll keep my eyes open in case I see something similar next time I go! If anyone has a clue about this, I’d love to know!

 

Trying out the wide angle macro technique

It’s been a while since I’ve gone on a leisure insect photography walk. Today I had the opportunity to walk around a small ecological garden in the middle of the city, where one of the students showed me a large caterpillar, Pachylia syces (ID by Dr. Andrew Warren). I took this shot with my usual 100mm macro lens.

However, having seen some fantastic wide angle macro work by Piotr Naskreki and other amazing photographers, I thought I’d give it a try. There’s still plenty of room to improve, but overall I’m quite pleased with my two first tries. They really do add a lot of context to the images!

I will definitely try this technique again soon! It works best with larger subjects, like beetles and frogs, but I really enjoy the added context.

Campus sweep (a.k.a. an early Xmas)

If any of you readers follow me on Twitter, you’ll know that I have a slight bias towards collecting arthropods by sweeping with an insect net. It lets you collect an incredible diversity of arthropods in a small area and with minimal effort. Sure, it helps that I live somewhere with an incredible biodiversity, but I still prefer sweep samples over all other collecting methods. (Next in the top three are light traps and active collecting). So after an afternoon of presenting theoretical projects on experimental design, we (my labmate and I) were ready to relax for a bit. We headed towards a little area of my U’s campus armed with nets and a small jar of alcohol, and after 10-15 min of walking around and getting asked what we were doing by people passing by, we ended up with a nice jar full of bugs.

Sure, it’s finals week, and we only have exams, projects, jobs and a plethora of other responsibilities, but I couldn’t help but sorting through the samples as soon as I got home. I was hoping to find what we dubbed “the mantis fly”, a fly with raptorial front legs belonging to the family Ephydridae (Ochthera sp.). My labmate found two in some sweep samples she did when we went to the field last year, and she then found another one in a sweep we did on campus, so naturally I had collector’s envy.

So I turned up the music, grab some coffee and start sorting; not two minutes after that I saw it: I had finally found one! Just look at those amazing forelegs!

I was pumped, so I kept sorting. I was surprised not only at the amount of crab spiders (family Thomisidae), but at their striking color patterns. Online I usually see white and yellow females, and I’ve found one or two males with green forelegs and stripes on the cephalothorax, but nothing like this! At first I thought that only the males were so boldly colored, but several female specimens proved me wrong.

Crab spider diversity with bold color patterns

Obviously, I was like a kid in a candy shop. Colorful specimens with weird shapes are a collector’s dream. Then I stumbled onto something that looked like a crab spider, but something was off; the abdomen was much slimmer, and when I looked at the eyes, the arrangement was nothing like the traditional thomisid pattern, which is 8 eyes (all more or less the same size) arranged in two almost parallel rows.

I think this is a lynx spider (family Oxyopidae) that has two greatly enlarged pairs of forelegs. This convergence isn’t unheard of in spiders; jumping spiders of the genus Lurio also have similar forelegs, but this is the first time I see it in lynx spiders.

I also found a few other interesting specimens, such as a parasitic wasp with a sculptured thorax, a myrmecomorph rove beetle, a spotted orb weaver and an iridescent tortoise beetle. All in all, this was a fantastic sweep, and I hope future visits hold even more surprises!

A light trap in the city

I have always been interested in biodiversity. The incredible array of shapes, sizes, colors, habitats and adaptations of organisms is something I find fascinating.

I have been fortunate enough to have done field work in many different locations, from beaches to the cloudy rainforest to the Andes, and as a result I have seen incredible forms of life, particularly insects: snake mimicking caterpillars, antlion larvae, tarantula hawks, lanternflies, wasp mimicking katydids, grasshoppers the size of my hand and an array of shapes, colors and behaviors that defy belief. Yet I’m aware that most people that live in cities will only see these organisms in TV documentaries; biodiversity in urban environments is usually much, much lower than in places with little or no human intervention. Part of my current work focuses on finding out just how diverse insects are in urban environments, how human intervention is affecting insect populations (or will affect them in the future) and what we can do to preserve or increase this diversity. That means that we have to photograph/collect insects, so last night we set up a light trap in an arboretum in the middle of the city. There were plenty of other light sources nearby, as well as streets, cars, houses, small shopping centers and the like, so I wasn’t expecting much; a previous attempt yielded only two microleps to the light trap. Still, I wanted to see what would come.

Not two minutes after setting up the trap, we had our first visitor, a crane fly. We had a few microleps, some bark lice, a few different beetles (Cerambycidae, Staphilinidae and other tiny ones), several wasps and a butterfly or two, among others. It was barren compared to any light trap I’ve set up in the field, but there was something interesting: it was surprisingly diverse! Out of all the insects that came to the trap, I only saw three species that had more than one specimen, and none had more than four. Almost all were very small (under a centimeter), save for three butterflies, one true bug and a wasp. Nevertheless, I considered it a success. More light traps will be set up in the coming months to see just how diverse the arboretum really is.

I’ll leave you with a few pics of some of the insects we saw! Any help with IDs will be greatly appreciated, particularly for the last one.

Interrupted by a lady(bug)

Today in class, my teacher, a classmate (a plant physiologist and an immunology grad student, respectively) and I were discussing our journal reviews for this trimester. We’re focused on presenting our work and thinking how we could improve our manuscripts when we were interrupted by this:

Image

 

I believe it is a Multicolored Asian Ladybug, Harmonia axyridis, although I’m not 100% sure. Regardless, it interrupted the discussion by flying across the room, and instead of ignoring it or removing it for being a distraction, we spent the next 15 minutes talking about how awesome ladybugs (and beetles in general) are. It was a good class!

An entomologist’s (and a photographer’s) bucket list

As a kid, I grew up reading about fantastic animals, creatures that were more incredible than anything my imagination could assemble: bats with leaf-like noses, hoatzins, axolotls, elephants, platypus, dinosaurs and countless arthropods and sea dwellers. As I grew up, I had the oportunity to learn more about these and other creatures, and in some cases, meet them up close.

While studying Zoology in college, I started a “bucket list”: animals, places or events I had to see (and photograph, if  possible) before I turned 30. In the past decade, I’ve crossed many off my list: I went to Angel Falls, fed an elephant, held a male Long-Tailed Sylph (Aglaiocercus kingi) and saw a tail-less whip scorpion in its natural habitat, among others.

During a field trip last weekend I saw one of the creatures I had longed to see for almost a decade: a scorpionfly. Yes, for many entomologists this isn’t a big deal, but they’re not that common down here. I was alone at the light trap at the time, since the two other researchers were ornithologists and had fallen asleep by 9:30 pm. I was doing a routine check when I looked down and there it was, stumbling on the floor; at first I thought it was a big crane fly, but when I looked closer I saw two pairs of wings and a face akin to the Egyptian god Set, and I knew that I was finally able to strike it off my list. It was a hangingfly (family Bittacidae) rather than a true scorpionfly (family Panorpidae), but still a fantastic find for me.

One of the worst things about finding it, though, was the inability to share my excitement with anyone; my friends at the station were asleep, no internet service and my friends back home would replace every song on my computer with the sound of a thousand vuvuzelas if I sent them an SMS at 2:30 am. I had to wait to return to civilization to share my excitement with fellow arthropod enthusiasts, since the ornithologists just said it resembled a mosquito on steroids.

Managing to finally strike that off my list has made me review it. Here are a few of the items:

– See a monarch butterfly migration completely covering a tree
– Swim with great whites (no playing heroes here, I’m perfectly happy to see them from inside a cage)
– Visit and photograph every one of my country’s national parks
– See a salamander
– Photograph a tiger beetle

Some are easier than others, but I hope to be able to cross them all off in the next couple of years.

Which items are on your list, and which have you managed to see/do?
