Hyptia thoracica (Blanchard)
Natural host.—Parcoblatta pensylvanica, U.S.A., Ohio (Edmunds, 1952a, 1953a, 1954).
Adult behavior.—Copulation was rapid, lasting only a few seconds. Blooms of Asmorrhiza longistylis were placed in a cage with adult wasps. The insects were attracted to and fed on the flowers (Edmunds, 1954).
Development.—Entire contents of oötheca are eaten by the single larva. Last instar larva overwinters inside the oötheca. Emergence in Ohio was around the middle of June. The emergence hole made by this genus was about 2 mm. in diameter. The hole was made at the top side of the oötheca near one end. Adult took about 65 minutes to emerge from the time its mandibles first broke through the oöthecal wall. (Edmunds, 1954.)
Distribution.—Canada, Ontario, U.S.A.: Connecticut to Wisconsin, south to Florida and Texas. Upper Austral to Tropical Zones. (Townes, 1951.)
