Chasing butterflies
across 6 continents

AZ's Lepidoptera Home | AZ's group at ETHZ


Dear ENVIRONMENTALIST: if you have concerns about the environmental impact of my collecting please visit this page. I am pretty sure that I am at least as passionate about butterfly conservation as you are, and that we are actually on the same team.


For me, collecting butterflies is very much linked to travelling the world. I have specimens from almost every place I ever visited. Some of these journeys are dedicated collecting trips, other are family vacations, and some are short getaways from business travel. Here are some recent accounts:
