That is so interesting that you posted this thread because every morning when I take my girls out to potty...there is ALWAYS at least 1 or 2 dead bee's on my patio.
I have to hurry out there to pick them up before my Abby the insect-eater gets to them before me...she likes Lizards, too! We've had a bad experience with both so, I do my best to keep my eye out for either to avoid a trip to the Vet's for the side effects that always follow...not fun or cheap!
I suppose I should take a peak around the roof since we don't have siding to see what I can see...
I just wonder why they are dead...do they die after they sting something or just because they are worn out by that Queen Bee...heeheehee!
