Greenhouse Camel Cricket
Tachycines asynamorus
Identification 6
An introduced species that often occurs in damp, dark locations around human habitation. Two conical protuberances between the antenna bases are unique to this species. It also has longer hind legs than other camel crickets that are typically splayed outward. The hind femorae are usually (always?) banded, which appears to be unique among camel crickets in Iowa. Some species of Ceuthophilus (I can't tell which species it is) have a single dark band just anterior to the knee joint, but not three dark bands like Tachycines.
The scientific name for this species was recently changed from Diestrammena asynamora to Tachycines asynamorus and many sources still list this species as Diestrammena asynamora.

Occurrence 6
Knutson and Jaques (1935) listed this species as present in Iowa, but there have been few records since. There is 1 BugGuide record and 1 iNaturalist record for Iowa. SCAN shows no records.
Habitat 6
Nearly always in damp, dark locations around human habitation like greenhouses, cellars, crawl spaces, basements, etc.
