Three summers ago I was hired as a Pennsylvania Apiary Inspector. When I started this job I thought back to my mentor Dr. Robert Berthold. He taught us bee diseases and pest by showing slides and using key descriptive words. This inspired me to start photographing various diseases and pest found inside and outside of the hive.

Colletes inaequalis congregation area
This is a large congregation of Colletes inaequalis, commonly known as the “Mining Bee.” This natural phenomenon occurs between March and July.

To view snapshots and full screen viewing of this Gigapan, see gigapan.org If you are lucky enough to find a congregation area, it is a sight to see. There can be hundreds to thousands of these small, excavated tunnels present on…
