Bug Spray is a new biweekly series by Dr. Norman Johnson, former Director of the Triplehorn Insect Collection at Ohio State. The subject is all insects and insect collection: history, biology, and fascination with the tiny creatures that surround us. Check out the first post and follow for more.

Bug Spray: the first dose

This is the official start date for short contributions from yours truly, now Professor Emeritus and retired Director of the Triplehorn Insect Collection. My goals are to promote the collection and…

Officially recruiting postdocs at GW. If you are interested in genetic novelty, structural variation, or evo genetics please get in touch! We have data sets on mulitple organisms with large population sizes (Drosophila, Megalonaias nervosa) and species in decline (fireflies, mussels, elephants).

We (@rileyshultz.bsky.social) tracked a recessive mutation from birth to death in honey bees. It causes ivory eyes. We collaborated across the continent to identify the mutation and it's downstream effects. Ultimately it is purified through selection on drones. We think Hamilton would be pleased!

Shultz @beeharpur.bsky.social et al. documented the trajectory of a spontaneous deleterious mutation from its origin in a single queen to its extinction, directly observing how haplodiploidy exposes recessive alleles to immediate purifying selection 🔗 doi.org/10.1093/molbev/msag156 #societyjournal

Look at this little lump. It's a barely 2 mm. springtail (class Collembola), which are hexapods (6 legs) but not insects. This one was at almost ten thousand feet in the mountains of Montana, living its best gummi life under a rock. #BugSky 🌿🐙

A macro photo looking down at a dark blue-gray creature called a springtail, on the surface of a pale brownish-yellow rock. The springtail is oval shaped, kinda squishy looking, with multiple body segments and a few sparse, short hairs. It has two short thick antennae.

The yarrow is also packed with an equally tiny wasp which I think might be Aprostocetus anodaphus (Eulophidae). It's an endoparasite of Ozirhincus millefolii (Cecidomyiidae), my tentative guess for the fly shown above. Both are found inside yarrow, at least in Europe. But I'm in Pennsylvania. #wasps

Tiny black wasp with pale yellow bands on a rather large, ovate abdomen, and with yellow legs that have black bands on the segments closer to the body.

Sometimes you've gotta go metallic to mimic your model! This common tropical hover #fly at the top is a convincing mimic of the local orchid #bees in the genus #Euglossa (bottom). #FlySchool2026 #Syrphidae: #Ornidia obesa Soltis Center, Costa Rica

Two metallic green winged insects on a white background, one at the top and one at the bottom. The top one is a hover fly and the bottom is an orchid bee.
