The evolution of food preferences in Coccinellidae
Vouchering DNA-barcoded specimens: test of a nondestructive extraction protocol for terrestrial arthropods
A protocol for the nondestructive extraction of DNA from terrestrial arthropods is described, using as examples members of the orders Acarina, Araneae, Coleoptera, Diptera, and Hymenoptera chosen to represent the ranges in size, overall sclerotization, and delicacy of key morphological characters in the group.
First records of Anisandrus maiche Stark (Coleoptera: Curculionidae: Scolytinae) from North America
Anisandrus maiche Stark, an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Pennsylvania, Ohio, and West Virginia. This is the twentieth…
Revision of the New World Lady Beetles of the Genus Olla and Description of a New Allied Genus (Coleoptera: Coccinellidae)
- N. Vandenberg
- 1 July 1992
Olla is shown to be part of a monophyletic assemblage of primarily Neotropical Coccinellini, united by shared characteristics of the genitalia and larval armature, and a hypothesis of the cladistic relations within Olla is presented using the sister genus Cirocolla as an outgroup.
Field guide to recently introduced species of coccinellidae (Coleoptera) in North America, with a revised key to north American genera of coccinellini
Extrafloral nectar feeding by ladybird beetles (Coleoptera: Coccinellidae)
New records of two Xyleborus (Coleoptera: Scolytidae) in North America
Barcode haplotype variation in north American agroecosystem lady beetles (Coleoptera: Coccinellidae)
The results support the general utility of COI barcodes for distinguishing and diagnosing coccinellid species, but point to possible limitations in the use of barcodes to resolve species assignments in recently divergent sibling species.
New insights into the phylogeny and evolution of lady beetles (Coleoptera: Coccinellidae) by extensive sampling of genes and species.
First North American records for Harmonia quadripunctata (Pontopiddian) (Coleoptera : Coccinellidae). A lady beetle native to the Palaearctic
- N. Vandenberg
—Harmonia quadripunctata (Pontopiddian), an Old World member of the tribe Coccinellini, is newly reported from three localities in the north eastern United States: Paterson and Westfield, New Jersey,…
