Identification

Four-banded stink bug hunter wasp is a large sand wasp. It is common in the United States and southern Canada east of the Great Plains. It is less common in Minnesota where it is at the northwestern extent of its range.

Adults are to ¾ (17 to 19 mm) long. The antennae of the male has 10 segments (flagellomeres) beyond the scape and pedicel. The female has 11 flagellomeres.

The exoskeletal plate covering the first segment of the thorax (pronotum) is short and collar-like. There is a rounded lobe on each side of the pronotum that does not reach the small plate covering the wing base (tegula). The plate on the upperside of the large middle segment (mesonotum) is entirely black with no yellow markings.

The abdomen of the male has seven visible segments. The abdomen is black with 4 pairs of spots on the female, 5 pairs on the male. Each pair of spots forms a band interrupted in the middle. The distance between the bands increases approaching the end of the abdomen. The spots in the last two bands are widely separated.

The forewings are clear. The submarginal cell is clear, not brown.

The legs are mostly yellow beyond the base (coxa). The third segment (femur) on the middle leg is not expanded at the tip. The first segment of the last part of the leg (tarsus), corresponding to the foot, is slender, not inflated.

Pronotum

The saddle-shaped, exoskeletal plate on the upper side of the first segment of the thorax of an insect.

 

Scape

On plants: An erect, leafless stalk growing from the rootstock and supporting a flower or a flower cluster. On insects: The basal segment of the antenna.

 

Tarsus

On insects, the last two to five subdivisions of the leg, attached to the tibia; the foot. On spiders, the last segment of the leg. Plural: tarsi.

Sand Wasps filmed at Strasburg, Ohio 8/15/2013 Video shows the wasps starting burrows and entering burrows dug previously. If you listen carefully at some points you can hear sand particles hitting the camera. In some scenes, paralyzed hemipterans (bugs) are being hauled into the burrows, where the wasp will lay an egg which will hatch into a larva to feed on the hemipteran, which remains paralyzed after being stung by the wasp. You can also see other insects entering the burrow, in particular small flies were common around the burrows and sometimes entered them. I think the flies are parasitizing either the paralyzed hempiterans or the wasp's eggs or larvae. This population has been at this site for over 10 years.
