Family Scoliidae (Scoliid Wasps)
Tribe Scoliini
I am fairly sure that the black-winged, red-tailed
wasps shown here are either Scolia dubia
haematodes or Triscolia ardens. Both are in the
tribe Scoliini. In late August 2025 these wasps
were also swarming the Baccharis salicifolia in
Warm Springs Wash, northeast of Hillsboro.
Distinguishing between Scolia dubia haematodes
and Triscolia ardens is difÞcult. The nominate form
of Scolia dubia has (generally) two yellow spots on
the upper abdomen and can be dismissed as a
possibility here.
