Thread-waisted Wasp

From time to time I have come across these small black flying insects while I have been out shooting and I have been curious about what type of insect that they were. So I looked them up and found out that they are a type of wasp called a thread-wasted wasp. They are members of the Sphecidae family and there are 728 species of them world wide.
In North America there are 206 species. Most are black in color, although some may also have some red, white, or yellow portions or may have a blue or green tinge. They are usually solitary and ground nesters. Adults eat nectar from flowers like this one is doing.
For propagating the thread-waisted wasp will paralyze an insect, typically a caterpillar or a grasshopper, or spider depending on the type of wasp, with its sting and then carry it to a ground nest. It will then lay an egg in the immobilized prey and cover the nest. When the larva hatches it will use the host as a food source and then pupate underground.
