Meloe americanus - female

Meloe americanus - Female
Martinak State Park, Caroline County, Maryland, USA
October 21, 2000
Size: 17 mm
I'm not entirely sure if this is M. americanus. See my comments at(1), based on publication by C.L. Staines (1983) The Meloidae of Maryland (Coleoptera), Maryland Entomologist 2(3): 41-52, which has a key adapted from Pinto and Selander to the Maryland species of Meloe. In regard to the punctation on the head and pronotum, I am calling this "sparse" as compared to the punctation seen on M. angusticollis(2) or on the unidentified Meloe species at(3). I would call the punctures on those latter two "dense" (on the head in particular). However, I am a bit confused because the punctures on my photo look somewhat "coarse" and the punctures on M. americanus are supposed to be "fine" in the paper by Staines. However, I'm going with M. americanus because Staines says that species is the only nocturnal oil beetle in Maryland and this beetle was found crawling on the ground in the woods on a chilly fall night.
Note: You must obtain a permit to collect insects in Maryland State Parks and Forests.

correct as indicated (M. americanus) -- J. Pinto
