Adelges tsugae
Hemlock Woolly Adelgid, HWA
Adelges tsugae, the hemlock woolly adelgid, is a small invasive sap-sucking insect native to East Asia. In eastern North America, it is a destructive pest of eastern hemlock (Tsuga canadensis) and Carolina hemlock (Tsuga caroliniana), causing extensive tree mortality and threatening forest ecosystems. The insect is named for the white, woolly wax coating that covers its egg sacs and protects the insects beneath. It reproduces asexually via parthenogenesis in North America, producing two generations per year.
Aleuroplatus
Aleuroplatus is a genus of whiteflies (Hemiptera: Aleyrodidae) established by Quaintance & Baker in 1914. Whiteflies in this genus are small, sap-feeding insects with powdery wax-covered wings. The genus has accumulated over 1,700 observations on iNaturalist, indicating moderate documentation of its species in the field.
Amorphicola pallida
Amorphicola pallida is a psyllid species in the family Psyllidae, first described by Tuthill in 1943. Psyllids, commonly known as jumping plant lice, are small sap-feeding insects that typically specialize on particular host plants. This species has been recorded from the central United States including Iowa, Kansas, Minnesota, and Nebraska.
Corythucha distincta
Corythucha distincta is a species of lace bug in the family Tingidae, first described by Osborn and Drake in 1916. The species is known from North America with records spanning much of the United States and Canada. Like other lace bugs in the genus Corythucha, it possesses the characteristic reticulated, lace-like forewings that give the family its common name. Two subspecies are recognized: Corythucha distincta distincta and Corythucha distincta spinata.
Ellescina
Ellescina is a genus of leafhoppers in the family Cicadellidae, subfamily Typhlocybinae. Species in this genus are small, delicate insects associated with vegetation. The genus is part of the diverse Erythroneurini tribe, one of the largest groups of typhlocybine leafhoppers.
Nigridonus
Nigridonus is a genus of leafhoppers in the family Cicadellidae, subfamily Deltocephalinae, tribe Platymetopiini. Established by Oman in 1949, this genus belongs to a diverse group of sap-feeding insects within the order Hemiptera. Members of this genus are poorly documented in scientific literature, with limited published information on their biology and ecology.
