Larvae and Pupae of the Species of Cryptochironomus (Diptera) in Michigan1

Abstract

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.

Taxonomical notes on the chironomid midges of the tribe Chironomini collected from the Ryukyu Islands, Japan, with description of their immature stages

“…However, the present pupae differ from that of Cr. 1905; Roback, 1957;Curry, 1958;Darby, 1962), but none of thern is identical with the present materials.…”

Chironomidae larvae from the lower Athabasca River, AB, Canada and its tributaries including macroscopic subfamily and tribe keys, indices for environmental tolerance and trait-based information for biomonitoring

“…They occur in coastal plains and piedmont plateaus (Hudson et al, 1990). Curry (1958) reported the larvae to occur in bottom deposits of pulpy peat and sands and in association with species of Certophylum and Potomogeton. Adult emerge in early July (Curry, 1958).…”

Effects of heated discharge and entrainment on benthos in the vicinity of the J.H. Campbell Plant, eastern Lake Michigan, 1978-1981 /

“…refers to a "group" of species undeterminable from larvae and was associated with the genera Chironomus and Paracladopelma . Morphology and taxonomy of other chironomid genera and species were determined from the following references: Lenz (1954), Roback (1957), Curry (1958), Beck and Beck (1969), Saether (1969, 1971, 1973, 1975, 1976, and 1977), Hirvenoja (1973), Maschwitz (1975), Jackson (1977), and Soponis (1977).…”
