Abaeis nicippe
Sleepy Orange
Abaeis nicippe, commonly known as the Sleepy Orange, is a medium-sized butterfly in the family Pieridae. The species exhibits seasonal variation in coloration, with summer individuals typically bright orange and winter forms showing darker, more heavily marked wings. It is known for its hilltopping behavior, where males patrol ridge tops and summits to locate females. The species has been documented engaging in aerial competitions with other males when pursuing females.

Agraulis incarnata
Gulf Fritillary
Agraulis incarnata, commonly known as the Gulf Fritillary, is a brush-footed butterfly in the family Nymphalidae. The species is widely distributed across the southern United States, Mexico, Central America, and South America. Adults are characterized by bright orange upper wings with black markings and three white spots on the forewing. The caterpillars feed exclusively on passionflower vines (Passiflora spp.), sequestering cyanogenic glycosides from their host plants for chemical defense. The species is a sporadic migrant in northern parts of its range, occasionally establishing temporary colonies before winter mortality.

Anteos maerula
Yellow Angled-Sulphur, angled sulphur
Anteos maerula is a large Pieridae butterfly commonly known as the yellow angled-sulphur. Its native range extends from Peru through Central America to Mexico, with occasional vagrant individuals recorded as far north as the central and eastern United States. The species is distinguished by its angular wing margins and substantial wingspan, making it one of the larger sulphur butterflies in the Americas.

Echinargus isola
Reakirt's Blue
Echinargus isola, commonly known as Reakirt's Blue, is a small butterfly in the family Lycaenidae. The species is native to Central America and the extreme southern United States, with regular northward migrations throughout most of the U.S. reaching nearly to the Canadian border. It has been documented visiting flowers of White Prairie Clover (Dalea candida) in Colorado, where multiple individuals may congregate on single blossoms. Very rare vagrant records extend into the southern prairies of Canada.

Euptoieta hegesia
Mexican Fritillary
Euptoieta hegesia, commonly known as the Mexican Fritillary, is a butterfly species in the family Nymphalidae found throughout North and South America. It is characterized by bright orange upper wings with black spotting and yellow-orange undersides lacking submarginal spots. The species has a wingspan of 2.5 to 3 inches and is active year-round in Mexico, with seasonal flight periods in the southern United States. Larvae feed on passionflowers and other host plants, displaying distinctive red coloration with silver spots and black spines.

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.

Macroglossum
Hummingbird Hawkmoths
Macroglossum is a genus of hawkmoths (Sphingidae) known for their rapid, hovering flight and diurnal or crepuscular activity patterns. The genus contains approximately 100 species distributed across the Old World, with the most extensively studied species being Macroglossum stellatarum, the Hummingbird Hawkmoth. Members possess elongated proboscises adapted for nectar feeding from tubular flowers. Several species exhibit migratory behavior, with individuals capable of long-distance movements across continental Europe and into Africa. The genus serves as an important pollinator group, with some species showing specialized coevolutionary relationships with particular plant species.

Hummingbird Hawk-moth, Hummingbird Hawkmoth, Eurasian Hummingbird Hawkmoth
Macroglossum stellatarum is a diurnal hawkmoth renowned for its hovering flight and long-distance migratory behavior. Adults feed on nectar from diverse flowers using an exceptionally long proboscis, and are significant pollinators across their range. The species exhibits complex visual learning capabilities and innate color preferences that guide foraging decisions. Populations in southern Europe may be resident and multivoltine, while northern populations depend on annual immigration from the south.

Megalographa biloba
Bilobed Looper Moth, Stephens' Gem
A noctuid moth in the subfamily Plusiinae with a wingspan of 38–44 mm. It occurs from the southern United States through Central and South America to Argentina, and migrates seasonally into northern United States and southern Canada where it produces one or two summer generations but rarely survives winter. The species is sometimes considered a pest on cultivated lettuce.

Pantala flavescens
globe skimmer, globe wanderer, wandering glider
Pantala flavescens is a cosmopolitan dragonfly species in the family Libellulidae, recognized as the most widespread dragonfly on Earth. It performs the longest known insect migration, with populations completing annual multigenerational circuits of up to 18,000 km between breeding grounds in Asia and Africa. The species exploits temporary freshwater habitats for rapid larval development, completing the life cycle from egg to adult in as little as 38–65 days. Its extraordinary dispersal ability is facilitated by broad wings adapted for gliding flight and utilization of high-altitude wind systems.

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.

Pieris rapae
small white, cabbage white, cabbage butterfly, small cabbage white, imported cabbageworm (larval stage), white butterfly (New Zealand)
Pieris rapae is a small to medium-sized butterfly in the family Pieridae, native to Europe and Asia and introduced to North America, Australia, New Zealand, and Hawaii. Adults are white with black wing markings; females bear two additional black spots on the forewings. The species is a significant agricultural pest in its larval stage, known as the imported cabbageworm, feeding on cruciferous crops. It has been extensively studied for its responses to climate change, with long-term data showing progressively earlier spring emergence in North America.

Tramea
Saddlebags, Saddlebags Gliders, Saddlebag Gliders
Tramea is a genus of dragonflies in the family Libellulidae, commonly called saddlebags or saddlebags gliders. Species are distributed across tropical and subtropical regions worldwide. They are characterized by colored bases on otherwise translucent hindwings that create the visual impression of carrying bags near the abdomen base. Members are medium to relatively large dragonflies known for sustained gliding flight and infrequent perching.
