Ohio Lepidopterists holds an annual meeting in January. Speakers present on wide ranging topics in the Lep world, including state wide monitoring results, interesting trips, and new scientific findings. Past speakers have included Kenn Kaufman, author of “Kaufman Field Guide to Butterflies of North America”, and Seabrooke Leckie, author of “Peterson Field Guide to Moths of Northeastern North America”. 

Join us for interesting topics in a relaxed atmosphere!

ID day and the Triplehorn Insect Collection at OSU

Join us at the Triplehorn Insect collection to help ID butterfly and moth specimens.


We can provide speakers on a variety of topics, as well as printed materials and brochures. Have a conference or meeting? We have a tabletop display and can provide a person to help talk about Ohio Lepidopterist

Butterfly Observation Group (BOG)

The bi-monthly meetings are currently on hold due to Covid issues and will resume when the Upper Arlington Library opens up it’s meeting rooms

The BOG meets every other month. During the period of time that butterflies are in flight, the BOG has field trips across the state of Ohio and neighboring states. During the colder months, the BOG holds meetings on topics such as gardening, Lepidoptera lifecycle, and where to find butterflies.

Harris's Three Spot Moth (Harrisimemna trisignata)

The Harris's Three Spot Moth caterpillar is unusual in the lep world. As the caterpillar grows, it sheds its skin. Instead of losing the head capsule, it stays attached. So, if you look carefully you can see two head capsules from earlier instars. Get too close and it may smack you with them. This and looking like bird poop from the top and side, and looking like a jumping spider behind, help the caterpillar stay safe from its enemies.
