Collections from several diversified habitats in Michigan yielded larvae belonging to the genus Cryptochironomus.Subsequent collections were made to obtain the immature forms for laboratory cultures from which the adult midge was obtained.The reared adults were then associated with their respective immature forms.Information obtained from the associated specimens and museum specimens of other investigators formed the basis of a key for the Michigan species.Thus, the larval and pupal stages for C. sorex, C. fulvus, C. blarina, C. digitatus, and one new provisional species are given. In addition to the larval and pupal morphology, other pertinent facts regarding the biology of the species are given when known.

AbstractCan. Ent. 103: 310-314 (1971) Larval forms of Chironomidae were collected on the U.S. Virgin Islands and Anegada, British Virgin Islands. A total of 16 species were found and seven of these were reared to the adult. The species represented 3 subfamilies, 4 tribes, and 12 genera. Species of the genus Chironomus were the most widespread and abundant. In addition, 4 species of Ceratopogonidae and 1 of Chaoboridae were collected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
