I found this small bumble bee drowned in my cat's outdoor water dish. Don't know the species, but it was a fairly small bumble bee - about the length of a typical European Honey Bee but much stouter. A close up of its head (click on the image for a larger file): 

Pentax K3 with reverse mounted SMC K 24mm f3.5, no additional extension (about 2.5x life sized.)  Two separate stacks combined, 111 exposures total.
