Microbembex - Microbembex monodonta - Male
Scotland Beach, Saint Mary's County, Maryland, USA
June 6, 2015
Looks like Microbembex based on the “Marginal cell in distal half [being] bent away from wing margin” as described in (1). Am I correct in concluding that this is M. monodonta based its being found in Maryland?
There was a fair number of these around in the drier sand areas of this Chesapeake Bay beach. Most were basically milling around but this one eventually dug a hole deep enough to disappear into - which I assume means it was a female.
Thanks in advance for the help.

Answered my own question; from what I can find M. monodonta is the only Microbembex species found on the east coast of the US. Discover Life contains one record of M. aurata from Illinois but nothing further east (link below)

Bohart and Horning (1) say there are 7 Microbembex species in the “continental United States” with the following ranges –

M. agyropleura: southern California, Arizona, Nevada, and western Utah
M. aurata : southern California to western Texas (Illinois)
M. californica: west of Continental Divide in U.S.; Sonora and Baja California in Mexico
M. hirsuta: western Texas and New Mexico
M. nigrifrons: west of 100th meridian in US.and Mexico
M. monodonta: east of Continental Divide, Canada to Panama
M. rufiventris: southern San Joaquin Valley, California

To those species, the Discover Life Microbembex pages add these 2 with records from North America –
M. evansi: Texas
M. elegans: California
