Guides
Aramos ramosa
Aramos ramosa is a moth in the family Cossidae (carpenter moths). Adults are known from Texas in the United States and the Mexican states of Quintana Roo and Yucatán. Flight records indicate adult activity in June and from August through October. Available information on this species is limited.
Comantella fallei
Comantella fallei is a small to medium-sized robber fly (10-15 mm) found in California and Colorado. Adults are active in early spring and late fall, an unusual seasonal pattern for Asilidae. The species is distinguished by a humpbacked profile, a slender spur on the front tibia, and a distinctive "Mohawk" mane of hairs on the thorax. One observation documents predation on a small wolf spider (Pardosa).
Crambus multilinellus
multinellus grass-veneer
Crambus multilinellus is a small crambid moth known as the multinellus grass-veneer, described by Fernald in 1887. It is found in eastern North America, with records from the southeastern United States through the Great Lakes region to Ontario. Adults have a wingspan of 20–22 mm and are active from March to September. The larvae feed on grasses (Gramineae).
Dyschirius interior
Dyschirius interior is a species of ground beetle in the subfamily Scaritinae, described by Fall in 1922. It belongs to a genus of small, typically psammophilic (sand-dwelling) beetles. Like other members of Dyschirius, it likely inhabits sandy substrates and possesses morphological adaptations for burrowing in loose soils. The species has been recorded from North America.
Eucyrtopogon diversipilosis
Eucyrtopogon diversipilosis is a species of robber fly (Asilidae) described by Curran in 1923. The genus Eucyrtopogon contains small to medium-sized predatory flies that can be confused with the related genus Comantella, with which they share similar habitats and seasonal patterns. Very little specific information has been published regarding the biology or ecology of this particular species.

Blackburn's earth-boring beetle
Geotrupes blackburnii blackburnii is a subspecies of earth-boring scarab beetle in the family Geotrupidae. It is a medium-sized beetle with entirely black coloration and a nearly impunctate pronotum, distinguishing it from the closely related G. splendidus. Adults are most commonly encountered in fall, particularly on mild days, and are frequently found on or near animal dung in high-quality woodland habitats. The species has a broad distribution across eastern North America.
Macromya crocata
Macromya crocata is a species of bristle fly in the family Tachinidae. It belongs to the tribe Nemoraeini and was described by Reinhard in 1968. The species is found in North America, where it occurs in forested habitats. Like other tachinid flies, it is a parasitoid, though specific host records for this species remain undocumented. Adults are active during late summer and fall, often observed visiting flowers for nectar.
Meganola phylla
Coastal Plain Meganola Moth
A small moth in the family Nolidae with a wingspan of 18–24 mm. Adults are active from January through October, with peak activity between April and August. Larvae feed on Quercus (oak) species. Previously treated as a subspecies or color variant of Meganola minuscula.
Megatibicen figuratus
fall southeastern dusk-singing cicada
Megatibicen figuratus is an annual cicada species native to the southeastern United States, commonly known as the fall southeastern dusk-singing cicada. It was originally described in the genus Neotibicen before being reclassified to Megatibicen. The species is characterized by its late-season activity period and distinctive dusk-singing behavior.
Oecothea
sun fly
Oecothea is a genus of small flies in the family Heleomyzidae, commonly known as sun flies. The genus contains at least 20 described species. Members are distinguished by long, perpendicular spines on the leading edge of the wing, a diagnostic feature for the family. They are most frequently observed in early spring and late fall, and are attracted to artificial light sources at night.
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.

testaceiventris
Tetraclipeoides testaceiventris is a small scarab beetle in the subfamily Aphodiinae, described by Fall in 1932. It belongs to a genus of aphodiine dung beetles found in North America. The species is known from scattered records across the Great Plains and south-central United States.
Trichomagdalis atrata
wedge-shaped bark weevil
Trichomagdalis atrata is a species of weevil in the family Curculionidae, first described by Henry Clinton Fall in 1913. The species belongs to the genus Trichomagdalis, whose members are commonly referred to as wedge-shaped bark weevils. Little is known about the specific biology of this species, though its genus name suggests association with bark habitats. The species is recognized as valid in current taxonomic databases.
Trichonephila clavata
Jorō spider, Joro Spider, Parachute spider
Trichonephila clavata, commonly known as the Jorō spider, is a large orb-weaving spider native to East Asia that has become established as an invasive species in the southeastern United States since approximately 2010. First confirmed in Georgia in 2014, it has expanded rapidly across multiple states through a combination of ballooning dispersal and human-mediated transport. The species is notable for its substantial size, striking coloration, and extensive golden webs, but poses minimal risk to humans due to small fangs and docile behavior. Its physiological adaptations—including higher metabolic rate, faster heart rate, and greater cold tolerance than its congener Trichonephila clavipes—suggest potential for continued northward range expansion.
