Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Disholcaspis prehensa
clasping twig gall wasp
Disholcaspis prehensa is a gall-inducing cynipid wasp native to California that induces distinctive galls on scrub oak and leather oak. The species exhibits heterogony, alternating between sexual and asexual generations that produce two morphologically different gall types. The asexual generation forms conspicuous mushroom-shaped twig galls with clasping bases, while the sexual generation produces small, hidden bud galls.

Eustala
humpbacked orb-weavers
Eustala is a genus of orb-weaver spiders in the family Araneidae, first described by Eugène Simon in 1895. As of November 2024, the genus contains 87 species distributed primarily across the Americas, from the United States through Central America to South America, with highest diversity in Brazil, Uruguay, and Argentina. Several species have been documented exhibiting specialized ecological relationships, including myrmecophily (living among ants) in Central American species that inhabit ant-defended acacia plants. The genus includes the well-known humpbacked orb-weaver, Eustala anastera, found across North and Central America.
