Agabus confinis
predaceous diving beetle
Agabus confinis is a predaceous diving beetle in the family Dytiscidae, belonging to the confinis-group within the subgenus Acatodes. The species has a Holarctic distribution, occurring in North America and the Palearctic region. Larval stages have been described from reared material in northern Sweden, with morphological characters enabling separation from other European Agabus species. It is one of approximately 36 species in the confinis-group, which has been subject to taxonomic revision in North America.
Perithous septemcinctorius
Perithous septemcinctorius is a parasitoid wasp in the family Ichneumonidae, subfamily Pimplinae. The species is known from detailed morphological descriptions of its final instar larva, which exhibits distinctive features including maxillary and labial palpi with more than two sensilla. It is recorded from Belgium and Norway. As a member of the genus Perithous, it is presumed to be a parasitoid, though specific host associations for this species remain poorly documented.
Phrypeus
Phrypeus is a monotypic genus of ground beetles (Carabidae: Trechinae: Sinozolini) containing the single species Phrypeus rickseckeri. The genus was described by Casey in 1924 and is considered taxonomically isolated within the supertribe Trechitae. Its phylogenetic relationships remain obscure; larval morphology studies have failed to link it definitively with any other tribe. The first-instar larva has been described and illustrated.
Protaetia fusca
Mango Flower Beetle, Mottled Flower Scarab
Protaetia fusca is a flower chafer beetle in the subfamily Cetoniinae, commonly known as the Mango Flower Beetle or Mottled Flower Scarab. The species has a broad distribution spanning tropical and subtropical regions of Asia, the Pacific, and has been introduced to the Americas including Hawaii, California, Florida, and the Galápagos Islands. Larvae develop in decaying wood of broad-leaved trees, particularly Ficus species, while adults feed on tree sap and ripe fruits. The complete life cycle takes approximately one year, with adult activity peaking during summer months.
