Ozark County, MO (Tom Riley)

Texas Plinthocoelium County Records


County Record Source: E.G. Riley, Nov. 2005

Adult Activity: July through September based on specimens in the Texas A&M University Insect Collection.

Larval Host: Larvae feed in the root crowns of Bumelia, Sapotaceae.


Adults attracted to fermenting baits. Members of this genus in the tropics give off an alarm pheromone when disturbed (e.g. when collected) causing conspecifics in the vicinity to take flight.

Similar Species: 

There are nine species of Plinthocoelium, but only the following two species reach the United States.

Plinthocoelium schwarzi (Fisher, 1914) - South Texas
Plinthocoelium suaveolens suaveolens (Linnaeus) - se USA (TX-FL-DE)
Plinthocoelium suaveolens plicatum (LeConte) - Texas, se Arizona, sw New Mexico, Sonora, Mexico.

Comments: Plinthocoelium suaveolens is highly variable (see photo links below), and P. schwarzi may prove to be a subspecies of P. suaveolens.
