Feather-legged scoliid wasps peak in July heat

July 21, 2026

Feather-legged Scoliid Wasps are the dominant insect across the sandhill longleaf this July — four sightings in a month outpace any other species. The females comb the pale sand beneath the pines, hunting scarab beetle grubs with surgical precision: each grub receives a sting that renders it motionless, then a single egg is laid inside before the wasp moves on. This specialization is so exacting that it requires exactly the kind of loose, well-drained sandhill soil this ecosystem provides.

Tiger bee flies work the same underground economy from a different angle, depositing their eggs near ground-nesting bee burrows and letting their larvae take over from within. That this layered parasitoid guild is active and diverse through the hottest weeks of a dry summer is a quiet indication that the sandhill soil community — scarab grubs, ground-nesting bees, and their hunters together — remains intact beneath the canopy.
