0091. An annotated checklist of the lady beetles (Coleoptera: Coccinellidae) of Iowa, U.S.A.
AbstractAn annotated list is presented for 81 species of lady beetles (Coccinellidae: Coleoptera) that occur in the state of Iowa, U.S.A., based on literature searches and a review of over 3500 specimens in institutional and private collections. The list includes new state records for Scymnus tenebrosus Mulsant, Diomus debilis (LeConte), Hyperaspis lateralis Mulsant, Hyperaspis deludens Gordon, Epilachna borealis (F.), and Subcoccinella vigintiquatuorpunctata (L.), as well as county records for the non-native species, Harmonia axyridis (Pallas). Collection records are discussed for Nephaspis oculatus (Blatchley), Hyperaspidius militaris (LeConte), Coccinella californica Mannerheim, and S. vigintiquatuorpunctata, which have Iowa records that are disjunct from their larger geographic distributions in North America. I also discuss collection records and the need for additional collecting of coccinellids in Iowa, especially Adalia bipunctata (Schneider), Coccinella transversoguttata richardsoni Brown, and Coccinella novemnotata Herbst, which were once common and widespread but have declined drastically over much of North America, including Iowa.
