Thread-waisted Wasp

The season for photographing insects on flowers is coming to a close. Here's one of this year's last  -- the lovely thread-waisted wasp, Ammophila procera, shiny black with silver streaks on the thorax and a wide orange band around the center. Halloweeny color scheme, right? Click to enlarge.
This adult is drinking nectar at flowers but these wasps start life on quite a different diet. After mating, the female digs a burrow in soft ground or sand and then captures a caterpillar or other insect and stings in into paralysis. She places it inside the burrow, lays an egg on it, seals up the burrow, and leaves. A meal of fresh caterpillar will be waiting right there when the larval wasp hatches.
