Expiscor (29 July 2013)

From the world of arachnology, entomology and beyond… Expiscor is here for you! Here are some things I stumbled across this week:

  • Mirror mirror on the wall… Nicky Bay with photos of a spider turning its abdomen into a multifaceted mirror.
  • Photo time! Another stunning shot from Adrian Thysse - this one of a crab spiders as prey. You can follow his blog here (and thanks to Adrian for allowing me to reproduce the shot, here)

  • Six Second Insects: a great use of the Vine app, from Morgan Jackson.
  • A Catan-style board game with ants. FUN! (thanks Alex Wild)
  • and even more from Alex Wild - an ant that is 30 million years too early.
  • Spider poop. Spider Joe posted an amazing photo of the stuff (see below); the solids are undigested prey material and the liquid is a slurry of guanine crystals. Wow. (um, and as Joe stated on twitter, Oreo cookie, anyone?)

Spider poop

  • Bird poop. I had some land on me earlier this week. Apparently that should only happen once every 195 years. (I take that as good luck). Thanks Lab & Field for the link!
  • Tweet of the week goes to my (young) colleague Dr. Dez:

  • First Impressions: a great piece of nature writing from Kim Moynahan.
  • Editors and authors of this Journal of Animal Ecology paper should be ashamed: “Who wears the pants” in the title of this paper.
  • The greening of Canadian Campuses. Hey, my campus is featured!
  • For Academics: The awesomest 7-year post-doc.
  • Alcohol-free whisky. Seriously, this doesn’t sound like a very good idea.
  • And finally, a Happy Birthday (today!) to my big sister. She’s awesome (and she writes books!)
  • For nature geeks everywhere… True facts about owls. I love this:

The Mottled Jumper: a new common name for a jumping spider

A couple of weeks ago I set up a poll so that you could help give a jumping spider a common name. This was all made possible thanks to a series of fun twitter conversations which ultimately led to the list of potential common names for Sitticus fasciger.

Crowdsourcing a common name received a bit of press (e.g., CBC Homerun, the afternoon radio show in Montreal), and this led to discussions about the process of giving species a common name. For the record, with about 20,000 described arthropods in Canada, fewer than 1700 have common names (you can refer to the Entomological Society of Canada’s list of common names). There’s a lot of work to do! There is a committee within the Entomological Society of Canada, and anyone can submit a common name - there is even a fillable form! However, the common name must make sense, and have some meaning that relates to the species biology, appearance, or life history. A group of experts will evaluate the proposal, and if accepted, a species can receive a common name. So, after this project with Sitticus fasciger, my work is not done: I will now proceed to get the selected common name officially accepted, and will eventually submit it for approval to the Entomological Society of America, also.

OK, enough of this… what about the poll results?

Sitticus fasciger: over a hundred people have spoken… and the common name selected is the Mottled Jumper. That name received over 45% of the vote. It is also my personal favourite - mottled refers to irregular arrangement of patches of colour, and is an accurate description of the spider.

In sum, THANKS everyone for taking part - it was a fun project, and hopefully there will be more to come in the future.

At the union of science and art: A giant, robotic spider sculpture

Very amazing stories sometimes come my way, and this one must be shared. Don Hardy (an artist, creator, and curious man!) approached me with a story and photographs of a 9 foot spider sculpture that he made. Don found me because of the spider bite story that came out a few weeks ago, and he and I immediately developed a rapport despite the fact that we live in different countries, and have different training (me, trained as a scientist; Don, trained as an artist). What do we share? A love of spiders: a love of their elaborate and unique anatomy, the way they move, and the way they have such an important place in our society - whether it be via adoration, fascination or terror.

So, let’s get right to the good stuff. Here’s what Don created.

The giant spider sculpture!

The giant spider sculpture!

I am simply amazed and astounded by this beautiful creation!

I asked Don to provide me a few detail about the story behind his piece of art. Here are some exerts from his story, and Don has kindly given me permission to post this story, and his photographs.

I wanted to build a model of a spider for many years. The existing models and toys that I have seen were not real enough for me to appreciate so I decided to build my own version of a spider model. I studied many varieties of spiders and decided to use a combination of huntsman and wolf spider for my project. The initial inspiration was a huntsman spider due to an interesting experience I had at a pawn shop a couple of years ago. I was in the market for an electric piano and found one at a local pawnshop here in the Atlanta area. It was a Kawai model 330 missing the legs so I got a deal on it for 200 dollars! I brought it home and noticed that it had outputs for external speakers so I didn’t need to use the internal speakers at all. I could hook it up to my larger amp and get a bigger sound. I decided to take the internal speakers out and use them for another project later on. As I was taking one of the speakers out a large Huntsman spider came out of the hole! You can imagine how alarmed I was! I admit I jumped a little bit but soon relaxed after I noticed it was dead and dried up. I put it up and started to take out the second speaker. Another large Huntsman fell out of the second speakers hole! An unlikely duet! I put it up and continued to set up the piano for my other amp. The piano worked just fine. It gave me two giant huntsman spiders to contemplate!

Don then proceeded to study, measure and use these spiders as a model for his spider sculpture. Here’s what happened next, in Don’s words:

I used approx. a 40:1 ratio which would make my sculpture about 9 feet across with its legs fully extended. I made probably 20 trips to the local home improvement store and spent about 2 months working in the basement measuring, sawing, gluing, carving and bolting together the various boards, etc. that would replicate a spiders legs, pedipalps, fangs, sternum, cephalothorax and abdomen. I made templates for the eyes, fangs and abdomen. This helped with symmetry, size relationships and outlines for cutting. I also added heavy duty springs for leg tension so it could be self supporting.

I decided to go with a wolf spiders face which looked more interesting and fearsome to me. The wolfspiders eyes were much bigger and menacing than the huntsmans. And the anatomy was similar enough to switch over to a wolfspiders face without much difficulty. Once the basic structure was completed I started studying many images of huntsman and wolf spiders to paint a pattern on top. I probably used about 20 cans of spray paint before I was satisfied with the pattern. I used some artistic license but still stayed true to basic patterns. These spiders are masters of camouflage and the coloration and patterns blend in perfectly with grasses and terrain.

Halloween was fast approaching and I was able to display it in my neighbors yard. Amazingly some of the smaller children were crying and running from it thinking it was real! At first I built it as a static sculpture without any plans for further development. As I started studying what I created I realized that there was plenty of room for adding wires, motors and cables to make the fangs move, the pedipalps swing up and down and the abdomen to swing back and forth. Back to the workshop to add additional lifeforce! After drilling and a few more trips to the home improvement store I had a spider that had fangs that moved, pedipalps that swung in and out and an abdomen that shook back and forth!

Don and his spider friend.

Now it must surely be finished?

It stayed this way for about a year and then I realized I could make the two front legs raise up and down if I installed an actuator and cables on the sternum. I even went a step further and added servos and switches to the actuator and everything else so I could operate all the moving parts with a wireless transmitter! I purchased a Futaba four channel transmitter and four servos. I attached the servos to the sternum carefully lining up the wires and rods. After much tweaking I got it working quite well. The dream had of building a giant mechanical spider was finally coming true!

Um, yes, this giant spider sculpture moves. IT MOVES! Here’s a youtube video to show the sculpture in its full glory:

In summary, I sincerely thank Don for doing this incredible project, and also being keen to share it with the world. His work is a wonderful union of science and art.

  • The macabre beauty of medical photographs, via the Smithsonian.
  • Your favourite movies as vintage treasure maps. Awesome.
  • In honour of the completion of this year’s tour de France, here are some amusing quotes from one of the more colourful riders, Jens Voigt. e.g., Having things organized is for small-minded people. Genius controls chaos
  • And to finish, I agree with Bug Girl: this is one of the nerdiest Entomology videos out there. Wow.

On the game of Academic Publishing

Back in March, I was asked to present a talk to Professors at Cape Breton University about finding success with Academic publishing. This was in part because of my own experience with publishing, but also in my role as Editor-in-Chief for The Canadian Entomologist. This talk took some time to put together, but it was a lot of fun to think in detail about how the publishing ‘game’ is changing, and how’s it is difficult to navigate - especially for early-career Academics.

In this post, I am pleased to share my presentation with you - I hope it is useful to some, and I hope it sparks discussion about finding success in publishing. I realize some things were missed, and the presentation itself is rather static and cannot capture the dynamic discussion that was part of the seminar given at Cape Breton.

Please share!

Expiscor (15 July 2013) - The Thank-You Edition

I’m currently on holiday, and was unable to put together a typical post of links of discoveries for Expiscor. I therefore thought it would be a nice change of pace to provide a short list of people who I rely on heavily for links and images that are published on Expiscor. This post is, therefore, a “thank you” of sorts - Expiscor would just not be possible without constantly seeing terrific content, and this depends on people promoting interesting stories on Twitter or Facebook, or through other means. Creating lists is far from a solitary activity - quite the opposite. It’s about a community, and the people below are one part of that community.

Here’s a list of great people who consistently provide terrific content (in no particular order):

  • Dr. Dez: an entomologist with broad interests, from photography, to odd stories, and a deep love of old literature.
  • Bug Girl: it would be hard to have a set of links about entomology without mentioning Bug Girl - she provides a great dose of entomology, often with sense of humour, wit and sarcasm. Check out her blog here.
  • Alex Wild: most people who follow Expiscor probably already follow Alex. Entomologist and photographer!
  • Morgan Jackson is one of my key sources for entomology news in Canada. A Dipterist (that’s OK with me!), a great guy, generous, thoughtful, and a man with a great sense of humour. (he has, by the way, helped me a great deal as I started my venture into the world of social media!)
  • Ainsley Seago: an American entomologist, currently in Australia. In addition to entomological content, Ainsley is a source of “art with a twist”, Thripsters, anyone?
  • More from Australia, Cameron Webb provides links about biting flies, medical and veterinary entomology, and so much more.
  • From South America, Daniel Llavaneras is a source for stunning photos and commentary about biodiversity in the tropics.
  • Over in Europe, Matthew Cobb, from Academia to Entomology, contributor to “Why Evolution is True” and historian.
  • Still in the UK, Simon Leather, amazing scientist, and source of great blogs and terrific papers with entomological content.
  • Flying Trilobite provides wonderful content, and as a science illustrator, someone I admire.
  • For photography, I also enjoy posts and images from Sean McCann and Adrian Thysse - brilliant work, and they are always happy to have their work posted on Expiscor.
  • For insights into the grad student mind, Barbara Frei, Carly Ziter, and Nash Turley are must-follow. They find and promote terrific comment, and themselves are thoughtful, articulate and, well, just a great source of inspiration.
  • Finally, you all need to follow Ed Yong. That is all.

….OK, I have missed some amazing people, and for that I apologize… when I’m on vacation again, I’ll do a “part 2”.

From the docks of a cottage, enjoy your week!

Help give this jumping spider a common name

There’s a small brown/grey mottled jumping spider that is very common on the exterior walls of my house. It’s curious, cute, always on the move. A few years ago I identified the species as Sitticus fasciger, a jumping spider known from many parts of Asia, and since the 1950s, from North America. It is now found in Quebec, Ontario, most likely other parts of eastern Canada, Manitoba, and many parts of the USA, west to Missouri. This species is synanthropic - meaning it lives in close association with humans. More specifically, it’s found most commonly on houses and buildings (at least in the Nearctic).

That photo by Thomas Shahan is really stunning, but I must admit that most individuals I have seen are more brown/grey, and less ‘vibrant’ that the photo above. Have a peek at this video of a female (taken at my house) for what I think is more typical coloration:

Little is known about the biology of this lovely little spider - some work by Matsumoto and Chikuni (1987), done in Japan, discusses its life history, and a few nice websites have videos and other summaries of diagnostic characteristics and summaries of its distribution. (here, by the way, is the original description by Simon). I’m not certain about the etymology of fasciger. In latin, it refers to a ‘bundle of sticks or rods‘, which is not that informative. As Morgan Jackson points out, in middle Irish it could mean ‘neckband‘ which might refer to some of the coloration on the cephalothorax or abdomen.

This species, however, is lacking a common name, and I seek your help in determining one!

Although there are a lot of opinions about using common names for insects/spiders, I am generally in support of this idea. I think a more general audience likes to use common names, and I think common names can provide a nice context and description that is often missed with a latin name. The Zebra spider (Salticus scenicus), for example, is a well known cosmopolitan species, and that common names says something about how the spider looks to most people. Similarly, the Dock (or Wharf) spider is a nice common name for Dolomedes tenebrous since a wharf is a very common habitat! I think it’s a pretty ambitious task to give all species a common name, but I do think more common species should be given a common name.

So, with that introduction, let’s pick a common name for Sitticus fasciger. I asked for suggestions on twitter, and discussed this topic with a few people. I have set up a poll, below, with some of these suggestions. I’ll leave the poll open for a couple of weeks (until 25 July), and then share the results with you. I will then work to get this name formally accepted by both the Entomological Society of Canada and the Entomological Society of America.
