First Records Of Megachile Apicalis (Hymenoptera: Megachilidae) For Illinois Found In Heavily Urbanized Areas Within The City Of Chicago, Andrea M. Gruver, Paul J. Caradonna
The Great Lakes Entomologist
We provide the first record of the non-native Megachile apicalis Spinola (Hymenoptera: Megachilidae) in Illinois. Thirty Megachile apicalis specimens were collected in the summer of 2018 in a highly urban area of Chicago, IL, USA. Our findings suggest that the range of Megachile apicalis appears to be rapidly expanding across North America, inward from both the East and Western Coasts. Megachile apicalis in Chicago has a broad activity period, can take advantage of abundant non-native floral food resources, and has competitive nesting behavior, all of which may facilitate its successful establishment in disturbed urban environments, as well as its continued …
Notes On The Nests Of Augochloropsis Metallica Fulgida And Megachile Mucida In Central Michigan (Hymenoptera: Halictidae, Megachilidae), Jason Gibbs
The Great Lakes Entomologist
Notes on the nesting biology of two ground-nesting species are provided from Central Michigan. A single nest of Augochloropsis metallica fulgida was excavated on 12 July 2014 in Shiawassee County. There were two female nest inhabitants. Examination of mandibular wear, wing wear and ovarial development suggests one female was acting as a worker caste. Also, a nesting aggregation of Megachile mucida was observed in Ingham County. Information on nest architecture and cell construction is based on excavations of several nests during 7–15 June 2014. Megachile mucida is recorded as a new host species for the cleptoparasite Coelioxys sodalis. This is …
