A False Honey Ant documented by students at Jemicy School in Baltimore Co., Maryland (2/23/2017). Determined by James C. Trager/BugGuide. First MBP record for Baltimore Co.
Only member of its genus currently recognized in our area. Found throughout much of North America, this species winters in underground nests and specializes in foraging in cold temperatures (BugGuide, 2014). Found in various forested habitats encompassing both dry upland forests and mesic lowland forests including both dense and open woodlands and woodlots; less frequently recorded from open area habitats including field edges and grasslands (See Frye et al., 2014).
Description
"Viewing Prenolepis from above should immediately reveal the distinctive hourglass-shaped mesosoma, a distinguishing feature of the genus, and the anteriorly broad then tapering gaster" (BugGuide, 2014).

Prenolepis imparis, commonly known as the winter ant, false honey ant, or false honeypot ant, is a species of ant in the genus Prenolepis.[1] The species is found in North America, from Canada to Mexico, nesting deep within the ground. Unusual among ants, Prenolepis imparis prefers lower temperatures, including near freezing, and is only active outside the nest during winter and early spring.[2]Prenolepis imparis enters a hibernation-like state called aestivation during the summer.
P. imparis secretes an opaque white liquid from its abdomen as a defense against other ants, including Linepithema humile.[3] The defensive secretions appear to be derived anatomically from the Dufour's gland and has been shown to contain a mixture of alkanes and alkenes including hexadecene, octadecene, tetradecene, octylcyclohexane, and hexadecane.[4] Secretions from P. imparis have experimentally been shown to often kill L. humile workers.[4]
