Megarhyssa atrata, also known as the black giant ichneumonid wasp, is a species of large ichneumon wasp. It is known from North America, [ 1 ] where it is found from Quebec , Michigan , Ohio and North and South Carolina to Florida .
They are generally black wasps, similar in appearance to some Tiphiidae or Thynnidae, with white or yellow markings developed to various degrees. The female oviposits her eggs into the nests of solitary bees , and the developing larvae consume both the host larvae and the supply of food provided for them.
