Ammophila nigricans Dahlbom 1843. This widespread eastern species has not been collected frequently in the state. Most records are from the SLP, with two specimens from Marquette County being the only records from the UP.
BIOLOGY: Nests are in sandy-clayey soil, the burrow being either oblique or vertical with a horizontal terminal cell. A single caterpillar, usually a noctuid, is used to provision the cell, with the genera Catacola, Euparthenos, and Zale reported as prey (Evans 1959, Krombein 1979).
COLLECTION DATES: 55 specimens, 17 June to 28 August, with most dates from mid-July to early August.
