I recently received this via email. It is an opportunity to contribute to a USGS research project. Note that no Lepidoptera are to be killed. They are only interested in larger (2″ wingspan) already deceased butterflies and moths. I asked about roadkill (roadside and car grill) and they said those were ok to send in. Contact USGS contact with any questions.
Curious—Is the condition the specimens arrive in not an issue? I’m thinking an envelope doesn’t offer much protection again damage.
