When I started teaching Invertebrate Zoology in the mid-1990’s, students were required to write term papers as one of the tools for evaluation. With a fairly heavy teaching load, this approach became somewhat unmanageable given relatively high enrollment, in particular since I feel that it is important to provide detailed feedback to each student so they can improve on their writing skills. Depending on a student’s skill level, reading, editing and marking a paper can be rather time consuming. After a few years, I therefore reverted to delivering a strictly lecture/lab based course with midterm(s), quizzes and (lab and lecture) finals, essentially the way I had been taught. Two years ago, with considerable trepidation, I decided to step out of my comfort zone and try the blog format. This turned out very successful from a number of perspectives. The students really liked it, and I derived direct benefit by learning about organisms I would likely never have read or heard about. I also enjoyed marking these blogs, because a blog is shorter, less formal, and leaves a lot of room for personal style when compared to a term paper, while still retaining the requirements of coming up with a suitable topic, as well as finding and citing primary literature effectively.
While many of the blogs were about non-arthropods, a fair number of students chose members of this taxon to write about. In this blog, I highlight student blogs that may be of interest to ESC members.
Lena Richter looked at “The Camouflage of Praying Mantids”. Most entomologists are familiar with the orchid mantis, but did you know that Phyllocrania paradoxa nymphs imitate ants?
Favourites for many students (and many arachnologists as well I should imagine) are the jumping spiders. Jessica Leach discusses Portia species in her blog “Jumping spiders: sex among cannibals”. Portia jumping spiders have been described as among the most intelligent of all arthropods.
Danielle New was fascinated by the use of tiny wasps for biological control, which she described in “Trichogramma, a Living Insecticide?” One has to marvel at the ability of these tiny wasps to work for us.
Insects provide inspiration for art, and Nicole Tweddle discusses the use of caddis fly larvae to create jewellery in her blog “Caddisfly (Order Trichoptera) Larval Diversity: The Unlikely Jeweller”. This blog was of particular interest to me, because many years ago at a meeting of the Entomological Society of America, I purchased caddisfly-manufactured earrings for my wife. They were not as exclusive as the ones featured in this article, however.
Madison Wong wrote about the not-so-pleasant effects of centipede venom in “The effect of venom in centipedes.” An arachnophile and former Prince George resident (who described his hobby/business of breeding tarantulas as an interest that went terribly wrong) kindly used to show his animals to UNBC students. One of the few critters he would not handle was his giant centipede!
“Giant Weta” or Wetapunga, the enormous anostostomatid crickets of New Zealand, was the topic for Amandeep Bhatti. Many of these large, flightless insects are threatened and thus of great interest.
Warren Noronha wrote about another species of jumping spider, “Phidippus audax: The Most Daring Spider.”Phidippus species are quite impressive as jumping spiders go. Where I live we have P. johnstoni, a closely related species.
Giant Scolopendra centipedes provided the topic for Brittany Fotsch. In “A giant in the under-foliage: Scolopendra gigantea” she ends by referring to centipedes as pets: “A 30 cm, 46-legged, bat-killing, venomous critter is not for everyone, but nevertheless even Amazonian giant centipedes need some TLC.”
Conrad Taylor’s blog “How I was out-fished by a spider” received a lot of attention when I tweeted the link some time ago. It differs somewhat from most of the other blogs because it is built around a personal experience, and I am sure that is the reason for the attention, at least in part. It certainly makes it an enjoyable read.
The use of transparency in a butterfly caught the interest of Erin Haugland, who wrote about “Greta oto: The Invisible Butterfly.” One of the adaptations to make this approach feasible is the presence of submicroscopic bumps change the refractive index of the wing to match the surrounding air. Who knew?
Ian Curtis wrote about “The Reindeer Warble Fly (Hypoderma tarandi): An Arctic Parasite,” an insect I knew a little about from my time in Sweden. I also got the opportunity to communicate with my Norwegian colleague Arne C. Nilssen, who gave us permission to use his fabulous photo of an adult fly. Arne did his Ph.D. research on bark beetles, which is how I knew him.
An assignment like this is bound to have at least someone looking at honeybees. Jared Peet wrote his blog “Apis mellifera: Un-bee-lievable Communication” about these important insects, and in a second course I taught, two students wrote honeybee related blogs.
Aphids have never been my favourite insects (sorry Simon Leather!) although I could have ended up working with them, early on courtesy of Dr. Jan Pettersson in Sweden. It isn’t an organism I would expect a student to pick, but Grant Usick found an interesting angle in his blog “Acyrthosiphon pisum: The little pea aphid that could.” Perhaps I have to reconsider?
Brooke Wiebe picked Acacia ants for her blog “Pseudomyrmex ferruginea: The ideal tenant.” I still remember a presentation by Dan Janzen about these fascinating little ants and how they have assumed the defense role of Acacia trees.
For no particular reason, I left out several blogs about horseshoe crabs and Crustaceans. The Crustaceans covered were fiddler crabs, tongue eating isopods, trapeziid guard crabs, pistol shrimp, pom-pom or boxer crabs, tadpole shrimp, Dungeness crabs, and the goose barnacle. And that leaves out all the other interesting invertebrates, of which cephalopods were the most numerous – no surprise there! Anyway, many students exceeded my expectations by a wide margin, and I really believe that it was the format that gave them inspiration to go the extra mile. I am sure Dezene Huber (who will take over after I retire at the end of this year) will improve on the course. Nevertheless, the students deserve credit for a job well done! I hope you will read a few of these blogs, and that you will enjoy them.
