    Maybe this might help to identify some of your wasp species.     Posted 3 years ago, modified 3 years ago

    What a great find! It's a really cool process to watch as they drill into the wood. If you're not familiar with the process, there are details (and video) here:
    Giant Ichneumon Wasp - Megarhyssa atrata Large, thin-bodied wasp. Females are very dark black and yellow. They are parasitoids of wood-boring insects in dead, deciduous trees.When a female is ready to oviposit her eggs, she rotates segments 8 and 9 of her abdomen and unfolds her intersegmentary membranes so that they form a disc 2 cm in diameter. The surface of this disc produces a secretion that disintegrates the wooden substrate and facilitates her ability to insert her ovipositor. After she lays her eggs on the surface of the host larva she completes the same rotational movements to remove her ovipositor from the wood and the stylus returns to its resting position. This entire process takes an hour. Geotagged,Giant Ichneumon Wasp,Megarhyssa,Megarhyssa atrata,Spring,United States,ichneumon wasp,ichneumonidae,wasp
