|Bumble bee robbing nectar|
Some flower visitors don't hesitate to rob nectar without paying their dues. They either don't bother or can't enter the flower the "legitimate" way, and thus, ensure picking up pollen along the way and delivering it to the next flower. Instead they take a shortcut, slashing the throat of the flower and going right to the source. Carpenter bees can be among the most notorious robbers because of their strong and sharp mouth parts that enable them to perforate the walls of a flower; but other large insects can be just as bad.

Tubular or trumpet shaped flowers are the most frequent victims of this larceny because their nectar is hard to reach. Here are some abelias that have been robbed. You can see the scar at the base of the flower.
Sometimes smaller bees or other insects take advantage of the shortcut and visit the wound, like this beetle, which also happens to parasitize the nests of bumble bees.

In this case something more tragic happened. A small bug ventured deep inside the flower and became tangled, its legs sticking out of the hole, and unable to go in or out or turn around. I thought that I may be able to help it and by the way find out the identity of the victim; but my clumsy old fingers couldn't perform this delicate task. I never found out who this innocent bystander was. Any guesses?
