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.

Exenterus amictorius
Exenterus amictorius is an ichneumonid parasitoid wasp introduced to North America that attacks sawfly larvae (Hymenoptera: Diprionidae), particularly during the pre-spinning eonymph stage. The species exhibits adaptive host discrimination behavior that changes during the host's spinning period, lacks discrimination initially but rapidly acquires and maintains this ability. It shows strong positive density-dependent responses to host abundance and has established successfully on multiple diprionid hosts across North America. In multiparasitism situations with the native E. diprionis, E. amictorius consistently survives due to faster larval development.

Pentodontini
rhinoceros beetles
Pentodontini is the most diverse tribe within the subfamily Dynastinae (rhinoceros beetles), containing over 100 genera distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart morphology in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.
