Argentine Ants have spent the past century following commerce around the world, aggressively subsuming the territories of native ants. However, a study by Meghan Cooling et al out today in Biology Letters reports a dent in the Argentine ant empire: Argentine ants had disappeared from 40 per cent of our sampling sites. In many other [...]

Insects and People – a class in what bugs you
This is the class I am teaching at the University of Illinois next spring: I asked May Berenbaum, who created this class years ago, about the main idea. She explained (paraphrase mine): I want students, 10 years from now, to see a bug on the sidewalk and appreciate it enough not to step on it. [...]
Monday Night Mystery
This odd-looking lump is, believe it or not, entomological. What is it? Points will be awarded to the first person to pick the identification, as follows: order (2 pts) family (3 pts) genus/species (5 pts) The cumulative points winner for the month of November will take home their choice of 1) any 8×10-sized print from [...]
Belated Answer to the Monday Mystery
Goodness. Time flies when you’re stuffed with turkey. I suppose I should post the answer to last week’s Mystery DNA before I post this week’s challenge: All ten points go to Ashley Troth, for picking both the species and the stop codons indicating the non-coding nature of the pseudogene. Also, two more points to “µ” [...]
Orb-weaving spiders have an ant problem
One measure of a predator’s ecological significance is the abundance of strategies prey adopt to avoid being eaten. And how ecologically significant are ants? They are enough of a problem to web-building spiders that the arachnids impregnate their webs with ant-deterring 2-pyrrolidinone: …ants are rarely reported foraging on the webs of orb-weaving spiders, despite the [...]
The exotic ant trade in perspective
A news story from Australia this morning reminds us how most pest ants move around the world: Fire ants have been found in a box of mining equipment shipped from the US to Queensland’s Western Downs, sparking fears the deadly ants may have spread. Staff at a Roma mining company found the fire ants at [...]
Monday Night Mystery
Here’s a snippet of DNA sequence from a mystery insect: ATACATGACTATTTTCTCTTCAAGATTCTAATTCACCTACGTATGATTTAATA ATTTTTTTCCATGATTTTGCTATAATTATTTTAACTTTTATTACAATCTTAATT TTATTTATTACACTTAGATTAATATCTAATCAATTTATTCACCGATTTTTATT AGAAAACCAAACAATTGAAATTGTATGAACTGTCCTTCCTATGTTTATCCTC ATTTCTATGGCTATCCCCTCAATTAAAGTACTTTATCTTACTGATGAAATTTT TAATGTTAACCTTACTGTTAAGGCTCTTGGTCACCAATGATACTGACTTTT This DNA is interesting because, although it has recognizable structure, it is not a gene. I will award 8 Myrmecos points to the first person who can explain- with reference to particular features of the sequence- how I know [...]
