Euschistus tristigmus
Dusky Stink Bug
Euschistus tristigmus, commonly known as the dusky stink bug, is a pentatomid species native to North and Central America. It belongs to the economically important genus Euschistus, which includes several brown stink bug species that are agricultural pests. The species exhibits adult seasonal dimorphism, with morphological differences between spring and summer generations. Research has documented its vertical distribution patterns in pecan orchards, where it shows a preference for canopy habitats compared to the ground-dwelling tendencies of its congener Euschistus servus.
Ribautiana ulmi
Ribautiana ulmi is a typhlocybine leafhopper in the family Cicadellidae, first described by Linnaeus in 1758. It is associated with elm trees (Ulmus), particularly wych elm (Ulmus glabra). Research has documented its distribution patterns within tree canopies, showing preference for more illuminated areas and basal leaves of branches. The species feeds selectively on palisade mesophyll cells.
Satyrium
Satyrid Hairstreaks
Satyrium is a genus of butterflies in the family Lycaenidae, commonly known as satyrid hairstreaks. Species in this genus are distributed across the Holarctic ecozone. Many species exhibit specialized ecological associations, including larval dependencies on particular oak species and mutualistic relationships with ants. Several species have been the focus of conservation concern due to habitat specificity and perceived rarity.
Satyrium favonius
Oak Hairstreak, Southern Hairstreak
Satyrium favonius, commonly known as the Oak Hairstreak or Southern Hairstreak, is a small butterfly in the family Lycaenidae with a wingspan of 22–38 mm. The species is distributed across the eastern and central United States, from southern New England and the Atlantic Coast south to peninsular Florida and west to central Illinois, southeastern Colorado, and the Gulf Coast. The larvae feed on Quercus (oak) species, consuming leaves, buds, and male catkins. The species overwinters as an egg.
Satyrium favonius ontario
Northern Oak Hairstreak
Satyrium favonius ontario, the Northern Oak Hairstreak, is a canopy-dwelling butterfly subspecies found in the northeastern United States. Its perceived rarity appears largely due to detection difficulties rather than actual low population numbers, as adults spend most of their time in oak canopies rather than at ground level. The subspecies has been documented feeding on non-nectar sources including oak gall exudates and honeydew. Listed as a Species of Special Concern in Massachusetts.
Somatochlora margarita
Texas emerald
Somatochlora margarita, the Texas emerald, is a dragonfly endemic to the United States with a highly restricted range in eastern Texas and western Louisiana. It inhabits river systems and is rarely observed due to its habit of perching in forest canopies. The species was described by Donnelly in 1962 and is considered one of the more poorly known North American emeralds.
