Head: Round; dark brown to black.
Male and female identical, eyes of female only slightly wider, barely discernable.
Antenna: Black, very short.
Thorax: Dark brown to black with rust hairs across shoulders; sometimes thorax is bald. Thorax sides may have some yellowish hairs which do not form a definite line.

Three sets of cross veins have a light mark on each side of the vein, called aureoles. One near base, one about mid-wing, and another small one below (or R4 + R5, M2 and CUP).
Legs: Dark brown with a row of spines on front shin (tibiae). Feet lighter.
Abdomen: Dark brown to black with small to large yellowish spots across each segment and a yellowish line across lower margin. Dark fringe mixed intermittently with some white on side edges of abdomen.

All season in southern U.S. Late May to August in the north.
larvae are hyperparasites (parasites of parasites), mainly of larvae of flies (Diptera, Tachinidae), as well as parasitic wasp larvae (Hymenoptera, Ichneumonidae) and caterpillars of the family Noctuidae.
Holotype as Anthrax morioides by Say, 1823. Type Locality: Missouri. Type destroyed.
Syntypes as Anthrax catulina by Coquillett, 1894. Type Locality: Washington & California. Apparently the 4 syntypes were lost from the United States National Museum, Smithsonian, Washington, D.C. per Evenhuis & Greathead (1999).
Anthrax georgicus wing is almost identical, often with a small, off-white round spot at mid wing. A. georgicus also lacks the aureoles on crossveins which are present on H. morioides.
