for your help, Brad. I wonder if a beetle that small can fly?

Flying insects run the whole gamut between large and tiny. For example, check out the family Ptiliidae. Some are less than a millimeter and fly. And many of the largest beetles can fly as well.

Usually (I think) the lack of flight in Coleoptera, which is not uncommon, is due to the lifestyle of the beetle. I imagine somewhere is a review of the topic, which would be an interesting read.
