They are called camel crickets, cave crickets, spider crickets, or sprickets. Among the places they live are in damp basements and garages. They are harmless. There are 150 different species of them in North America, Entomology Today reports. Until recently, the site says, the camel crickets found in basements and garages were native species. But no more.
A citizen science project by researchers at North Carolina State University found that 90 percent of the camel crickets observed by the researchers or reporting citizens were greenhouse camel cricket (Diestrammena asynamora), a non-native species from Asia long known in greenhouses, but not in basements.
To make things even more interesting, photographs of camel crickets sent from the northeastern US appear to depict Diestrammena japanica, which hadn’t been formally reported in the US before.
