Infernophilus castaneus
Infernophilus castaneus is a species of ground beetle in the family Carabidae, described by George Henry Horn in 1882. The genus Infernophilus belongs to the tribe Lebiini within the subfamily Lebiinae. The specific epithet 'castaneus' refers to a chestnut brown coloration. Distribution records indicate presence in the United States and North America.

Neomida bicornis
Two-horned Darkling Beetle
Neomida bicornis, commonly known as the Two-horned Darkling Beetle, is a small species of darkling beetle in the family Tenebrionidae. The species is characterized by the distinctive horn-like projections on its head, from which its specific epithet derives. It has been documented across eastern and central North America, with observations ranging from Canada to the United States. The species is attracted to artificial light sources at night.

Onthophagus
Onthophagus is the most species-rich genus in the subfamily Scarabaeinae (true dung beetles), containing over 2,200 species across approximately 30 subgenera. The genus has a global distribution spanning all major biogeographic regions. Members are characterized by extreme diversity in male horn morphology, which has made them a model system for studying sexual selection and evolutionary developmental biology. The genus name derives from Greek roots meaning 'dung-eater.'

Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.
