In total, forty-nine species of springtails were found. Four are described as new to science (Onychiurus pipistrellae n. sp., Pygmarrhopalites fransjanssens n. sp, P. incantator n. sp, and P. salemensis n. sp), four may represent new species but there is insufficient material available to prepare full descriptions (two species in the genus Superodontella, one in Pseudachorutes, one in Sminthurides), and three others (Ceratophysella cf. brevis, C. cf. lucifuga, and Folsomia cf. bisetosa) are identified to species, but differences from the nominal species suggest further studies may indicate the Illinois populations represent distinct forms.
