Anisoptera is the suborder of dragonflies, distinguished from damselflies (Zygoptera) by their larger, stouter bodies, eyes that touch or nearly touch at the top of the head, and wings held horizontally away from the body at rest. The name derives from Greek roots meaning 'unequal wings,' referring to the broader hindwings compared to forewings. With over 3,000 described species globally, dragonflies represent one of the most ancient lineages of flying insects, with fossil relatives dating to the Triassic Period 250 million years ago. Adults are aerial predators with exceptional flight capabilities and vision, while larvae are aquatic predators found in diverse freshwater habitats.

Speyeria coronis, the Coronis fritillary, is a North American butterfly in the family Nymphalidae. It ranges from Baja California to Washington and eastward to Colorado and western South Dakota, with one historical report from Alberta. The species exhibits apparent migratory behavior in central Washington populations. Larvae feed on Viola species.
Stictocephala stimulea is a treehopper species in the family Membracidae, first described by Van Duzee in 1914. Treehoppers in this genus are characterized by their enlarged, often ornate pronotum that extends over the body like a helmet or thorn. The specific epithet 'stimulea' suggests possible resemblance to or association with stinging organisms, though this refers to appearance rather than actual sting. Like other membracids, this species likely feeds on plant phloem sap using piercing-sucking mouthparts.
Tetramesa is a genus of minute phytophagous wasps in the family Eurytomidae comprising over 200 described species. Members are exclusively associated with grasses (Poaceae), where they typically induce stem or inflorescence galls. The genus exhibits pronounced host specificity, with most species restricted to a single grass species or closely related congeners. Several species have been deployed as biological control agents against invasive grasses, including T. romana for giant reed (Arundo donax) and candidate agents for medusahead (Taeniatherum caput-medusae) and African lovegrass (Eragrostis curvula). Adults feed on nectar. Recent phylogenomic studies have synonymized the genera Aiolomorphus and Cathilaria within Tetramesa.
