This Bumblebee is stealing nectar from the base of this Moneyplant flower. These insects are crafty creatures, they have learned how to go directly to the source of the nectar, bypassing the pistil and stamens. It is common to see holes in Columbine spurs made by these bees.

An empty Oak gall. This gall was once the home of a wasp larva. The larva from this gall was lucky, it was able to mature into an adult, as indicated by the small escape hole.

This is an empty Oak wasp Gall photographed in the fall.
