About Charley Eiseman

I am a freelance naturalist, endlessly fascinated by the interconnections of all the living and nonliving things around me.

Connecticut BioBlitz

A month ago Dave Wagner got in touch with me and Julia, saying we were needed at the 2016 Connecticut State BioBlitz on June 3 and 4. He wanted to make sure leafminers were properly represented in this attempt to break … Continue reading

No, Not Leafcutter Bees
