Here comes the sun! Waking up at 6:30 for breakfast (eggs, rice, beans, freshly made tortilla) is easy when the sun is up and the flies are flying. Everyone was itching to get out into the jungle, and so we headed up towards the peak of the nearest mountain. We definitely had some great collecting, with each of us finding a few specimens of our respective study/hobby groups, and I’m fairly happy with my photos from this morning. Getting exposures correct in the shadows of the jungle can be difficult, and there are a lot of black backgrounds, but it certainly beats nothing! After making it up to the top of the mountain (altitude = ~1300m) we came back down to our lunch while rain clouds started to blow in. With perfect timing we got back to the lodge only minutes before the rain hit and just in time for lunch (pasta, fried pork chop, coconut & dulce squares). The food here has been awesome, and Patricia has been spoiling us! After lunch we proceeded to pin the day’s catch and make our notes for the day. With the rain still coming down all afternoon, the only thing left to do was sit in a hammock and hope the insects came to us. A bit of a slow afternoon, but the morning made up for it! After dinner (broasted chicken, mashed potatoes, broccoli, and rice) the rain had finally ceased, so we stepped out for a quick night walk to look for herps, then sat and looked at the Milky Way, visible to the naked eye so far from the light pollution of major cities.

There were a ton of reptiles and frogs hopping around the trail today, so many that I think we may have seen more species here than I have seen in all my other trips combined!

The clouds seem to come and go in the blink of an eye, revealing dramatic landscapes of rolling mountains one second, and concealing all but the closest of trees the next.

Well, it seems that the rain is determined to keep us lodge-locked for the rest of the day. Hopefully tomorrow morning will be as nice as today was so we can get out and find some more flies!

Beto had us believing that our dinner tonight was actually Crested Guan (a large native chicken-like bird); he is certainly a big fan of practical jokes!

Tonight was the night of the giant wolf* spider it seems, with an orange species courting Andrew’s laptop (which is also orange) and a black species waiting for Nichelle to come to bed. Being inquisitive, we figured we’d try feeding them with some freshly caught moths. The orange species put on a good show, pouncing on the moth the moment it hit the floor and then running between Joel’s legs while he was squatting, while the black species didn’t seem to be hungry. Both were released outside before bed!

Despite having experience with feeder roaches back in Canada, Andrew had a bit of a freakout after a large cockroach landed on his shoulder in the common room. Hilarity ensued!

MTC…

* – I say wolf spider with a grain of salt as I’m not an arachnid expert by any means, and Neotropical spiders are a little more diverse than back home!

Welcome to a new feature for the blog, Bug of the Day! Each day I’m away in Costa Rica I’ll be highlighting an insect I came across, and challenging each of you to come up with the identification! Coveted BioPoints will be awarded to the first person to post the correct family name (5), common family name (2), and if you know the subfamily, you’ll get an additional 15! I’ll provide the answers and award points after I get back to Canada, so make sure to check back in to see how you did! Remember BioPoints can be redeemed for framed photos when you get a total of 200! See you tomorrow!

Costa Rican Adventure – Day 3 – El Copal Reserve

Time to head down south for some fun in the jungle and the largest gathering of Dipterists this grad student has yet to see! I figured I’d try and make a travelogue of short entries for this whole experience day-by-day (including the days when I have no internet, so expect some days with multiple posts) which will include some of the highs, lows and miscellaneous stories each day.

Today, we go into the jungle! After a relatively slow, but very good, breakfast at the Adventure Inn, we piled into what was to be our first of three taxis to begin our journey to El Copal Reserve. Our driver Roland was extremely helpful, especially when he realized that the city we were trying to get to was much further than he had originally thought when we had agreed on a fare the night before! Without missing a beat, he drove us to Cartago, found us a 4×4 taxi, and made sure that the driver was ok with splitting what we had paid Ronald! Altogether some amazingly nice people. Mario then drove us through the winding and progressively worsening roads to El Humo, where we met up with our final driver of the day, Maya. After loading all of our gear (and Andrew) into the trunk, we set off for one final, wild ride up into the mountains. As we climbed higher and higher up the mountain and the clouds began to draw closer and closer, the habitat around us changed from sugar cane and cattle farms to beautiful tropical rain forest with flowers blossoming all around. Before we knew it, Maya had us into the lodge with only a few minor scrapes on the underside of the truck! Since Gil is the only one able to converse in Spanish, the rest of us got to look around and ogle over all the amazing places we’d be exploring in the next 4 days, while he arranged our ride back to San Jose and how the lodge worked. The station itself is rustic, but comfortable, and our hosts couldn’t be friendlier, or better cooks! Beto and Patricia welcomed us with smiling faces and freshly prepared lunch (rice, palm heart, coleslaw, and fried beef) and after getting settled into our rooms, we headed off into the jungle to find us some flies!

The weather today wasn’t overly great with constant overcast, making the collecting a little slow and the photography rather uninspiring, but we each came out of the jungle 4 hours later with new insects we had never seen before and ideas about how to make the next few days as productive as possible! A quick rest to pin our insects and tally our birds, then off to dinner (vegetable soup, rice & a burger pattie) and pleasant conversation with Beto and Patricia (thanks to Gil), topped off with dulce, a raw, condensed sugar cane product that was a great way to finish off the evenings meal. Talk of an evening hike quickly ended as each of us realized our beds were calling ever so loudly! Perhaps tomorrow night…

The sections of San Jose and Cartago that we drove through today were some of the better looking Latin American towns that I’ve had the chance to travel to. No mountain-side slums, few run down buildings, plenty of people out dressed for work and ready to go! And the driving was far and away the safest I’ve seen south of the USA!

We heard Total Eclipse of the Heart in both Spanish and English on the way to El Copal, in 2 different taxis… what are the chances?

The drive from San Jose to El Copal was about 2 hours, including 2 taxi changes and some mountain road construction.

The bird fauna here is not what we were expecting, with more lowland Caribbean species around than we thought we’d see.

When we mentioned we studied flies, Beto asked if we knew Monty Woods or Jeff Skevington, who both work in Ottawa at the Canadian National Collection! Jeff is actually my co-advisor, and had been at the station only 2 weeks before we got here. Small world!

Speaking of small world, I happened to notice that the t-shirt Beto was wearing on our arrival was from the YMCA of Hamilton-Burlington, two cities that are about a half hour from Guelph. This is getting weird.

Costa Rican Adventure – Day 2 – San Jose

Time to head down south for some fun in the jungle and the largest gathering of Dipterists this grad student has yet to see! I figured I’d try and make a travelogue of short entries for this whole experience day-by-day (including the days when I have no internet, so expect some days with multiple posts) which will include some of the highs, lows and miscellaneous stories each day.

Overall today was probably the least eventful travel day I think I’ve ever had, which is good news for my stress levels, but really lame for this report….

Had the nicest TSA agents despite them all coming off the night shift, and only one person letting a little power go to their head.

Flight from Detroit–>Dallas didn’t offer any snacks or entertainment. I wish airlines would stop being so cheap and provide some customer service again! Seriously, a 2.5 hour flight with only a Dr. Pepper offered? Come on!

Lunch in Dallas airport, m’eh. Overpriced and under flavoured, but not the worst I’ve had. At least the chairs were comfortable…

Flight from Dallas to San Jose was alright as well, although we misunderstood the time change and were getting a little concerned when we were 20 minutes late for our touchdown without an explanation from the cabin crew! Turns out they don’t use daylight savings time down here… good to know! At least they served a meal on this flight, although nothing special or good. Also, apparently American Airlines no longer accepts cash for food, drinks, or headphones. That’s right, you need to pay $2 by debit or credit if you forget your headphones at home! I’ll pass thanks!

Started and finished another popular science book on taxonomy and biodiversity today, watch for a review in the coming weeks after I get home!

Staying at the Adventure Inn while in San Jose over the next few weeks. Seems great with nice rooms and a great pool that I look forward to testing later this week!

Bonus real life joke: A dipterist tries to walk into a bar but gets stopped by the plate glass window, gains first hand experience of what his flies must feel! (It wasn’t me either)
That’s it for tonight! We’re off to El Copal Lodge tomorrow to scout some new locations for collecting, and I’m guessing there won’t be any internet access. No worries though, I’ll be taking notes and expect a bunch of blog posts on Sunday when we come back to San Jose! Hasta luego!

Costa Rican Adventure – Day 1 – Detroit

All my work has been finished, paper submitted, and websites complete! Time to head down south for some fun in the jungle and the largest gathering of Dipterists this grad student has yet to see! I figured I’d try and make a travelogue of short entries for this whole experience day-by-day (including the days when I have no internet, so expect some days with multiple posts) and include some of the highs, lows and miscellaneous stories each day.

Flying out of Detroit this time to save some money ($400CDN for roundtrip to San Jose? Yes please!) means a longer car ride and an extra night away from home. Bummer.

We got the friendliest US Customs agents I think I’ve ever dealt with, with all 3 being really friendly and helpful, and no sign of a power trip! The guy doing our paperwork was especially great, asking a bunch of Diptera questions and breezing through the paperwork with no trouble!

Of course I realized 45 minutes down the road that I wore my good shoes and not my field shoes, and that I left half our supply of nail polish remover (it’s our method of choice for killing insects) sitting on the kitchen table, but if that’s the least of the mistakes then things will be just fine!

Free wifi in hotels = awesome.

Not having to get up at 0-dark-thirty to catch a flight also = awesome.

That pretty well sums up day 1 (who knew Detroit was this much fun…), but we go international tomorrow, and a day spent in airports should make for some more interesting stories. See you from Costa Rica!

Natural-born talent is something of a rare occurrence, with athletes like Mantle or Gretzky, or composers like Beethoven or Bach only coming along once or twice a generation. But does natural-born talent apply to a field like taxonomy? Are some people more adept at recognizing the differences and similarities between species, perhaps better connected to the “natural order”? In her book, “Naming Nature; the clash between instinct and science”, Carol Kaesuk Yoon examines not only this idea but also provides an historical account of how taxonomy has been done, from early hunter-gatherers to today.

Howdy Stranger(s)! It’s been awhile since my last post, but I’ve got a good excuse: I got married!! Yep, some crazy lady said yes two years ago and June 19 was our big day! We couldn’t have asked for a better day, with beautiful weather (the wedding was on the beach of Lake Huron), lots of friends and family, and all sorts of fun!

Thanks to Adam L. for the photo!

I couldn’t ask for a greater partner to travel through life with, or one who puts up with each and every pause to check out a fly, the hours spent with a camera pressed to my face, and the field trips that take me away. Not to mention she let me use insects as table names, put plastic bugs on the tables to complement the centrepieces and butterflies on the cake! She’s definitely my greatest catch! <3

This morning, undergraduate worker and entomologist-in-training Stephen Luk brought in a special little creature that he found in his backyard (click to enlarge):


Hammerhead flatworm on wood Bipalium Planaria

Neat, but what is it you ask? It’s a hammerhead flatworm (Bipaliidae) which he found under some bark. Although I’m not 100% confident about what species it is, I’m fairly certain it is the introduced Bipalium adventitium. These little carnivores are predators of another introduced invertebrate, earthworms. Dindal (1970) reported that once Bipalium latches onto its prey, it sucks away with its pharynx (mouth-like structure) and liquefies large sections of the earthworms integument before ingesting its victim section by section.

This individual was about a 1.5 cm long and constantly on the move, making for a tricky photo shoot! The first image was taken with only the Nikon 105mm VR lens and SB-800 speedlight, but to gain some added magnification I shot the remaining images with extension tubes. Generally when I’m shooting macro subjects with limited depth of field, I strive to have the eyes in focus to allow the viewer to “connect” with the subject. But what about a creature that doesn’t have eyes in the traditional sense? Well, I went for what I believe are light-sensing sensilli (larger crop of above photo):

It took quite a few tries to get a good shot with the small depth of field provided by the extension tubes, but it was worth the effort to see such a special little invert up close and personal!

I took a short break this morning to clear my head and get back into this photography thing, so I headed over to the University of Guelph Arboretum and went looking for flies. It became readily apparent that not picking up a camera for 8 months was going to make it a learning process all over again! And the first lesson? Charge your flash batteries! One shot into the day and I realize my SB-800 is dead in the water. Crap… luckily my shooting buddy also uses Nikon equipment, so while he was shooting I was collecting, and vice versa. Problems solved right? Well, lesson 2 quickly became apparent; check your settings! I had switched to shooting JPEG this winter for a family function! Crap… a quick switch back to RAW format with hope those first few shots were ok and won’t need much editing (JPEG files don’t handle heavy editing well) and back to work I go.

Well, at least something worked out! (Click to enlarge)

The rest of the morning was spent finding the body control and breathing necessary for macro work, and by lunch time I was feeling almost back into the swing of things! I definitely need to make the time to go out more regularly this summer, and remember, check, double check, and triple check your equipment each time you go out!
