Boloria selene
Small Pearl-bordered Fritillary, Eurasian Silver-bordered Fritillary, Silver-bordered Fritillary
Boloria selene is a medium-sized fritillary butterfly with a trans-Eurasian and North American distribution. The species exhibits complex population dynamics including bivoltine life cycles with distinct behavioral and developmental differences between spring and summer generations. In Europe it is known as the small pearl-bordered fritillary; in North America it is called the silver-bordered fritillary. The species serves as a grassland habitat indicator and has been extensively studied in the context of conservation management including prescribed fire and grazing regimes.

Cardiochiles is a genus of braconid wasps with nearly cosmopolitan distribution. Species are larval endoparasitoids, primarily attacking lepidopteran hosts. The genus includes economically significant species used in biological control, particularly against noctuid pests in agricultural systems.
Colletes compactus
polyester bee, plasterer bee, cellophane bee
Colletes compactus is a solitary ground-nesting bee in the family Colletidae, native to North America. Like other members of its genus, it constructs subterranean burrows lined with a distinctive cellophane-like secretion produced by the Dufour's gland, earning the common name "polyester bee" or "plasterer bee." The species nests in aggregations in sandy soils, with females provisioning individual brood cells with a semi-liquid mixture of pollen and nectar. Males emerge before females and actively patrol nesting areas seeking mates.
Colletes hyalinus
polyester bee, plasterer bee, cellophane bee
Colletes hyalinus is a solitary ground-nesting bee in the family Colletidae, native to North America. The species belongs to a group commonly known as polyester bees or plasterer bees, named for the distinctive cellophane-like lining females create in their underground brood cells using secretions from the Dufour's gland. Three subspecies are recognized: C. h. hyalinus, C. h. gaudialis, and C. h. oregonensis. Like other members of the genus, this species exhibits protandry, with males emerging before females.
Colletes hyalinus gaudialis
polyester bee, plasterer bee, cellophane bee
Colletes hyalinus gaudialis is a subspecies of polyester bee in the family Colletidae. Like other members of its genus, females construct solitary underground nests lined with a cellophane-like secretion from the Dufour's gland. This waterproof coating protects the semi-liquid pollen and nectar provisions for developing larvae. The subspecies is found in North America and shares the general biology of other Colletes species.
Dufourea monardae
Beebalm Shortface Bee, monarda dufourea
A small sweat bee in the family Halictidae, commonly known as the Beebalm Shortface Bee. Females measure approximately 7 mm, males 6–7 mm. The species exhibits sexual dimorphism in head shape, with females having a strongly protuberant face and males possessing a longer head. It is an oligolectic specialist, collecting pollen exclusively from bee balm plants (Monarda spp.). Active primarily during July and August across its North American range.
Macropis nuda
Dark-footed Yellow Loosestrife Bee
Macropis nuda is a small, ground-nesting solitary bee in the family Melittidae, native to northern North America. It is a highly specialized oligolectic species that forages exclusively for floral oils and pollen from Lysimachia ciliata (Primulaceae). The bee exhibits unique adaptations for oil collection, including dense white scopae on the posterior tibiae that use capillary action to hold oils. It is univoltine, with offspring hibernating as pupae in cocoons until the following spring.
Mastophora
bolas spiders, American bolas spiders
Mastophora is a genus of orb-weaver spiders in the family Araneidae, commonly known as bolas spiders. These spiders have abandoned the typical orb-web construction of their relatives and instead hunt using a unique method: they produce a single droplet of sticky silk suspended on a thread (the "bolas") and swing it to capture flying prey. Adult females are nocturnal moth specialists that use aggressive chemical mimicry, releasing sex pheromones to attract specific male moth species within range of their bolas. The genus includes 15 species in the United States, with Mastophora cornigera being the only species found in California.
Osmia
Mason Bees
Osmia is a large genus of solitary bees in the family Megachilidae, commonly known as mason bees. The genus includes approximately 500 species worldwide, with many species native to North America. Mason bees are named for their use of mud or other masonry materials to construct and seal nest cells. They are important pollinators of agricultural crops and native plants, and several species are managed commercially for orchard pollination. Unlike honey bees, mason bees are solitary, do not produce honey, and rarely sting.
Osmia cornifrons
Horn-faced Mason Bee, Horned-face Bee
Osmia cornifrons is a solitary mason bee native to Northern Asia, widely managed as an agricultural pollinator. The species was first introduced to Japan in the 1940s for apple pollination and subsequently to the northeastern United States in 1977. It is recognized by distinctive horn-like projections on the lower face of females. The bee exhibits protandry, with males emerging 2–3 days before females. It has been documented as established in Canada since at least 2017. Populations remain stable and have not shown rapid expansion compared to the accidentally introduced congener O. taurus.
Osmia pumila
Osmia pumila is a solitary mason bee native to eastern North America. It is strongly associated with forest habitats, where it performs spring pollination of wildflowers and possibly some timber trees. The species nests in pre-existing cavities such as hollow stems or holes in wood, sealing brood chambers with mud. Research indicates it is one of the most common forest-associated bee species in the eastern United States, with populations increasing as forest cover has regrown since the early 1900s.
Pholetesor ornigis
Pholetesor ornigis is a braconid parasitoid wasp specialized on Phyllonorycter blancardella, the spotted tentiform leafminer. It is a significant biological control agent in apple orchards. Adult flight peaks occur in mid-June and late August, with males emerging earlier than females. The species demonstrates clear host age discrimination, preferentially parasitizing intermediate instar larvae.
Speyeria mormonia
Mormon fritillary
Speyeria mormonia, commonly known as the Mormon fritillary, is a small montane butterfly distributed across western North America from the Yukon to California and Nevada. The species exhibits extreme protandry, with males emerging at least two weeks before females, leading to skewed adult sex ratios toward males. It occupies diverse habitats including rocky mountainsides, meadows, grasslands, and forest clearings, with populations typically occurring in small, semi-isolated patches. Multiple subspecies have been described, reflecting the species' broad geographic range and high genetic variability.
Sphex pensylvanicus
Great Black Wasp, Great Black Digger Wasp
Sphex pensylvanicus is a large, solitary digger wasp native to North America. Females construct underground burrows and provision them with paralyzed orthopteran prey, primarily katydids, for their larvae. Adults feed on nectar from diverse flowering plants and serve as pollinators. The species exhibits protandry, with males emerging before females in the breeding season. Despite their formidable size and appearance, they are not aggressive toward humans and sting only when handled.
