Catorhintha flava
Catorhintha flava is a species of leaf-footed bug in the family Coreidae, described by Fracker in 1923. It is distributed in Central America and North America, with records from Mexico and Texas. Like other members of Coreidae, it possesses the characteristic leaf-like expansions on the hind tibiae that give the family its common name. The specific epithet 'flava' refers to its yellow coloration.
Eurema boisduvaliana
Boisduval's Yellow
Eurema boisduvaliana, commonly known as Boisduval's yellow, is a butterfly in the family Pieridae. It is found from Costa Rica north to Mexico, with regular seasonal migration to southeastern Arizona, southwestern New Mexico, and southern Texas. Rare strays have been recorded in southern Florida. The species inhabits subtropical forests, forest edges, scrublands, roadsides, and pastures.
Eurema mexicana
Mexican yellow, wolf-face sulphur
Eurema mexicana is a medium-sized yellow butterfly in the family Pieridae, primarily distributed in Mexico with occasional northward strays into the southwestern and central United States. The species is distinguished by a distinctive black forewing border forming a 'wolf-face' or 'dog-face' pattern, and exhibits seasonal color variation on the wing underside. Males patrol hilltops and open areas seeking females throughout the day.
Eurema salome
Salome yellow
Eurema salome is a small yellow butterfly in the family Pieridae, commonly known as the Salome yellow. It ranges from Peru northward through tropical America and is an extremely rare migrant to the lower Rio Grande Valley in Texas. The species inhabits forest openings, edges, and roadcuts, with adults active year-round in the tropics and from August to September in southern Texas.
Gymnochiromyia flavella
Gymnochiromyia flavella is a small yellow fly in the family Chyromyidae, measuring 1.5–2 mm in length. It is characterized by distinctive head and thoracic setation patterns that aid in identification. The species is distributed across the Palearctic region, with confirmed records from Denmark, Norway, and Sweden.
Macronaemia episcopalis
Episcopal Ladybird
Macronaemia episcopalis is a small lady beetle species in the family Coccinellidae, known by the common name Episcopal Ladybird. Adults measure approximately 3.25–4 mm in length. The species is distributed across North America from Ontario and New York westward to Yukon and northern California, with additional records from Canadian provinces including Alberta, British Columbia, and Manitoba. The genus Macronaemia currently contains three described species.
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.

little yellows
Pyrisitia is a genus of small yellow butterflies in the family Pieridae, commonly known as "little yellows." The genus was established by Butler in 1870 and is sometimes treated as a synonym of Eurema. Species in this genus are characterized by their diminutive size and yellow coloration, and they occur in the Americas. The type species and most members are found in North, Central, and South America.
Pyrisitia dina
Dina Yellow
Pyrisitia dina is a small yellow butterfly in the family Pieridae, distributed across the Caribbean, Middle America, and southern North America. The species is one of several yellows in the genus Pyrisitia, which are often associated with open, sunny habitats. Adults are typically active year-round in tropical regions and during warmer months in temperate areas.
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.
