Habropoda laboriosa
Southeastern Blueberry Bee, Blueberry Digger Bee
Habropoda laboriosa is a solitary ground-nesting bee in the family Apidae, native to the eastern United States. It is an oligolectic specialist pollinator of blueberries (Vaccinium spp.), for which it is the most efficient known pollinator due to its buzz pollination behavior. The species is active for only 3-5 weeks annually, synchronized with early spring blueberry bloom. It nests in aggregations in sandy soils and has been estimated to provide $20 per individual in blueberry pollination services.
Liris apicipennis
Liris apicipennis is a species of solitary wasp in the family Crabronidae, tribe Larrini. The genus Liris contains over 260 species worldwide, with most diversity concentrated in tropical regions. Liris species are among the earliest solitary wasps to appear in spring, as females overwinter as adults. Like other members of its genus, L. apicipennis likely hunts crickets as prey and constructs underground nests, though specific biological details for this species remain poorly documented.
Pardalophora
coral-winged grasshoppers, orange-winged grasshoppers, Haldeman's grasshoppers, Saussure's grasshoppers
Pardalophora is a genus of band-winged grasshoppers in the family Acrididae, subfamily Oedipodinae, tribe Hippiscini. The genus contains at least four living species distributed across the Nearctic region. Species in this genus are notable for their brightly colored hind wings, which are concealed at rest but revealed during flight. Some species, such as Pardalophora phoenicoptera, are distinguished by overwintering as nymphs rather than eggs, resulting in early adult emergence in spring.
Rhionaeschna californica
California Darner
Rhionaeschna californica, the California darner, is a medium-sized dragonfly in the family Aeshnidae. Adults are distinguished by bright blue diagonal spots on the abdomen and exhibit sexual dimorphism in coloration and eye color. The species occupies aquatic habitats across western North America and Central America, with larvae requiring several years of aquatic development before nocturnal emergence as adults.
Stenosphenus
Stenosphenus is a genus of longhorn beetles (family Cerambycidae) first described by Haldeman in 1847. The genus contains approximately 22 described species distributed across North America from the eastern United States through Mexico and into Central America. Some species exhibit specialized host associations with particular tree genera, particularly hickories (Carya). At least one species, Stenosphenus notatus, is notable for overwintering as an adult—an uncommon life history strategy among eastern North American cerambycids.
Stenosphenus notatus
Stenosphenus notatus is a longhorned beetle (Cerambycidae) native to eastern North America. It is notable for its exceptionally early spring emergence, appearing during the first warm days of late March and disappearing before most other longhorned beetles become active. The species is closely associated with hickory trees (Carya), where larvae develop beneath the bark of dead limbs. Adults overwinter, an unusual life history strategy among eastern U.S. cerambycids.
