Three New Argyresthia Moths with Jacob Gorneau

New Species

Have you ever seen a series of fine squiggles in a leaf? Those might be leaf-mining moths in the genus Argyresthia. These tiny moths are closely linked with many agricultural crops, but factors including sampling bias and their small size mean we don’t know as much about them as we’d like. Jacob Gorneau and his team examined material from Guatemala and described three new species.

An insect-lover from childhood, Jacob has always been fascinated by moths, and these Argyresthia moths are no exception. They’re a small group both in number (with only 200 species) and in size (approximately 1/8th of an inch or smaller), but there’s a lot to learn about them, especially in relation to their host plants. Listen in as Jacob tells us all about his work, his future plans, and why we should care about these tiny animals.

Jacob Gorneau’s paper “Three new species of the genus Argyresthia Hübner, [1825] from Guatemala, with notes on host plant evolution and Nearctic taxa (Lepidoptera: Argyresthiidae)” is in Volume 51 Issue 201 of SHILAP Revista de lepidopterología.
