Explanation of Names
Ammophila W. Kirby 1798
'sand lover'
61 spp. in our area(1), >200 total(2)
11-38 mm (most species 20-25 mm)
Medium-sized black wasps with a relatively long petiole ("thread-waisted"), and usually with orange on the abdomen.
Podalonia are similar, but typically have the bulbous part of the abdomen bent upward and lying above the distal end of the petiole; whereas in Ammophila the abdomen is typically straight or bent downward at the distal end of the petiole --see figures A & C in(3)
Ammophila vs Podalonia
Generally, males have weaker reddish markings than females, are more slender, and lack a tarsal rake on the front legs.
Identification to species difficult.
Holarctic; widespread in NA
Summer into early fall. In NC, Apr-Nov (depending on species), typically May-Oct(4); in MI, Jun-Oct, typically Jul-Aug(5)
Adults visit flowers. Larva feed on caterpillars and sawflies provisioned by the adult female.
Life Cycle
Parasitoids on caterplillars and sawflies. A burrow is dug by the female and an egg is laid in the paralyzed host in the burrow. May be several generations per year.
