Species roeweri (Eumesosoma roeweri)
Central US:
Texas, Louisiana, Oklahoma, Arkansas, Kansas, Missouri, Nebraska, Iowa, South Dakota, North Dakota, and Wisconsin.

Also recorded from Boyle County, Kentucky, which was regarded as an introduction (Cokendolpher 1980), but should be the focus of a future molecular study.
Considered a specialist in prairies and grasslands.
Northern states (Dakotas, Minnesota, Iowa, Nebraska, and Kansas): Adults from late July to early October; immatures from early May to August.

Southern states (Oklahoma, Arkansas, Louisiana, and Texas): Adults year round; immatures from February to late May.
Life Cycle
"Limited information suggests oviposition takes place in the autumn, with eggs hatching in the spring (late winter in warmer climates) and sexual maturation occuring by summer. Specimens maintained in the laboratory do well on a diet of beer and sugar water, but lettuce, cockroaches, and moths are eaten as well; no cannibalism was noted." --Cokendolpher 1980
