Agallia quadripunctata
Four-spotted Clover Leafhopper
Agallia quadripunctata is a leafhopper species in the family Cicadellidae, commonly known as the Four-spotted Clover Leafhopper. The species was described by Provancher in 1872, with the basionym Bythoscopus quadripunctatus. It belongs to the subfamily Megophthalminae and tribe Agalliini. The species has been recorded in the iNaturalist database with over 1,700 observations, indicating it is relatively well-documented.

Collaria
grass bugs
Collaria is a genus of grass-feeding plant bugs (Miridae: Mirinae: Stenodemini) established by Provancher in 1872. The genus comprises 14 recognized species distributed across the Neotropical and Afrotropical regions, with several species documented as agricultural pests of forage grasses and wheat. Species such as C. scenica and C. columbiensis have been studied extensively in Colombia, where they impact dairy production in the Bogotá plateau region. The genus is characterized by its association with Poaceae (grasses) and its potential for significant population increases under favorable climatic conditions, particularly during El Niño events.

Macropsis ocellata
Macropsis ocellata is a species of leafhopper in the family Cicadellidae, described by Provancher in 1872. It belongs to the subfamily Eurymelinae and tribe Macropsini. The species has been recorded from scattered localities including Florida, the District of Columbia, Corsica, and parts of Central Asia (Astrakhan, Ferghana), suggesting a wide but patchy distribution. As with other Macropsis species, it is likely associated with woody host plants, though specific ecological details remain poorly documented.
Plagiognathus fuscosus
Plagiognathus fuscosus is a species of plant bug in the family Miridae, first described by Provancher in 1872. It belongs to a large genus of mirid bugs commonly associated with vegetation. The species has been documented across northeastern and temperate regions of North America.
Spangbergiella viridis
Spangbergiella viridis is a species of leafhopper in the family Cicadellidae. It is classified within the subfamily Deltocephalinae and tribe Hecalini. The species was described by Provancher in 1872. Available information is limited to taxonomic classification and basic nomenclatural data.
