I've been quiet for some time, busy with many things and with going through 4000 insect images. Here are some images of bumblebees. On May 11 I found this bumblebee sitting on my front doorbell. Perhaps it was warming itself using what little energy the light gave off. The other two images are of a Common Eastern Bumble Bee - Bombus impatiens and a Tricolored bumblebee - Bombus ternarius.
