Dielis trifasciata, also known as the three-banded scoliid wasp, is a species in the family Scoliidae.[3]

Description and identification

Dielis trifasciata typically have a body length of 10–15 millimetres (0.39–0.59 in),[4] though males of the subspecies D. t. nassauensis can reach up to 19 millimetres (0.75 in).[5] The females have yellow bands on the three anterior abdominal segments.[6] These bands are broad in the nominate subspecies, D. t. trifasciata but very narrow in the subspecies D. t. nassauensis. In males, the last three abdominal segments are black, and the scutellum has a single yellow band. The males of D. t. trifasciata are distinguished from allied species in part by the extensively yellow clypeus.[1]

Biology

These parasitic wasps lay eggs on larvae of the scarab Phyllophaga portoricensis.[4] Adult scoliids feed on nectar and possibly pollen.[7]

Distribution

Dielis trifasciata is present in southern Florida, the Bahamas, and in most of the Greater Antilles.[4][1]

Subspecies

There are two subspecies of D. trifasciata:[8]

  • Dielis trifasciata nassauensis (Bradley, 1928)
  • Dielis trifasciata trifasciata (Fabricius, 1793)
