Podalonia sericea Murray 1940. A wide-ranging,
western North American species (Krombein 1979), P. sericea
reaches its easternmost limit in Michigan. It has a shoreline dunes
distribution within the state. No inland records have been found.
BIOLOGY: At Warren Dunes State Park (Berrien Co.), females were flying along old dune crests overgrown with herbaceous vegetation. Prey are presumed to be noctuids, as Hicks (1933) listed Homoptera salicis Behr and Zale lunata (Drury) as prey in California.
FLOWER RECORDS: Euphorbia corollata.
COLLECTION DATES: 25 specimens, 3 July to 23 August.
