Biology

Excavate shallow, single celled nests in friable soil.
The female provisions her nest with a single moth caterpillar usually of
the family Noctuidae. The burrow shaft is filled in with raked soil and
small pebbles, which are compacted by the female. Females hunt their
subterranean cutworm prey by antennating on the surface of the ground.
Once a caterpillar is detected she digs down, retrieves the prey and
stings it multiple times. She carries the paralyzed caterpillar beneath
her body and hides it while constructing the nest. The caterpillar is
dragged backwards into the burrow and a single egg is laid on the first
or second abdominal segment (Gess & Gess, 2014). Important
pollinators of orchids (Steiner et al. 1994). |
