This medium-sized, orange Ichneumon Wasp is a Swallowtail Butterfly's nemesis.
Ichneumon wasps in the Trogus genus have shorter bodies than the eye-popping Giant Ichneumons. The orange-red color of the wasp is similar to that of Paper Wasps. This species has a more rounded bottom than Paper Wasps. Its black wings are dark, but still translucent. Legs are a lighter shade of orange. Orange antennae blacken at the tips.
This type of wasp is a parasite to Swallowtail larvae. A female wasp will lay an egg on a caterpillar and it will get cocooned inside the chrysalis. There it will hatch and begin feeding on the developing pupa, killing it before it can morph into a butterfly. The mature, winged adult wasp exits the case by oozing a chemical on it that softens the inside wall enough to break out.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Ant, Bee, and Wasp Anatomy

Thorax: Contains various vital parts such as the aorta and nervous system.
Abdomen: Contains various organs including the heart, gut, venom glands, and anus.
Legs: Ants and Bees have three pairs of legs attached to the thorax (center-body section).
