Cicinnus melsheimeri
Melsheimer's Sack Bearer
Cicinnus melsheimeri is a sack-bearer moth (Mimallonidae) widespread in the eastern United States and Rocky Mountains. It is one of only two Cicinnus species recorded from the United States and is morphologically and genetically distinct from the southwestern C. chambersi and Mexican C. mexicana. The species shows variable brown shading along wing margins and possesses distinctive male genitalia with elongated vincular arms. Despite being relatively common in the East, it remains rarely collected in western portions of its range.
Cynipoidea
Gall Wasps and Allies
Cynipoidea is a superfamily of small wasps comprising approximately 3,000 described species across seven extant families, with many undescribed species estimated. The group exhibits diverse life histories: while the family Cynipidae (gall wasps) are phytophagous and induce plant galls, the majority of species are parasitoids or hyperparasitoids of other insects. The superfamily is taxonomically challenging, with family-level identification historically difficult until the publication of a comprehensive illustrated key in 2020.

Greya solenobiella is a small moth in the family Prodoxidae, first described by Walsingham in 1880. It occurs in the western United States from southwestern Oregon through California, inhabiting grassy areas within dry to moderately moist oak and mixed deciduous forests. The species has a narrow wingspan of 9.5–14.5 mm. Its larvae are specialized seed-feeders on Yabea microcarpa, a plant in the Apiaceae family.
Heterocampa pulverea
Eastern White-blotched Prominent
Heterocampa pulverea is a moth species in the family Notodontidae, commonly known as the Eastern White-blotched Prominent. It occurs in oak forests across eastern North America. The species was formerly treated as a subspecies of Heterocampa umbrata but is now recognized as distinct.
Hyphantrophaga virilis
Hyphantrophaga virilis is a tachinid fly (family Tachinidae) known to parasitize caterpillars of the California Oak Moth (Phryganidia californica). The species was described in 1924 and occurs in North America. Like other tachinid flies, it develops as an internal parasitoid, eventually killing its host. Records indicate it is one of several parasitoids associated with oak moth population dynamics along the California coast and in Oregon.
Liometopum occidentale
velvety tree ant, Western Velvety Tree Ant
Liometopum occidentale, commonly known as the velvety tree ant, is a species of ant in the subfamily Dolichoderinae native to western North America. The species is frequently misidentified as carpenter ants (Camponotus spp.) due to shared morphological traits including polymorphic workers, a smooth convex thoracic profile, and wood-excavating behavior. This misidentification has led to underreporting of its significance as a structural pest in California, Oregon, and Washington. Colonies are large and polydomous, with worker populations estimated between 40,000 and 60,000 individuals.
Phortica
Phortica is a genus of small flies in the family Drosophilidae, subfamily Steganinae. Several species are medically significant as biological vectors of the zoonotic eyeworm Thelazia callipaeda, which causes ocular infections in humans, domestic animals, and wildlife. The genus includes at least five species in Europe and the Middle East, with P. variegata and P. okadai being the best-documented vectors. These flies exhibit unusual zoophilic feeding behaviors, including lachryphagy (tear-feeding) in adult males of some species. The genus has gained increasing attention due to climate-driven range shifts and expanding transmission of thelaziosis.
Platycerus quercus
Oak Stag Beetle
Platycerus quercus is a small stag beetle in the family Lucanidae, commonly known as the Oak Stag Beetle. It is distinguished from other North American stag beetles by its relatively modest size and reduced mandibles in males. The species is widely distributed across eastern and central North America, with associations to oak-dominated forests. Both adults and larvae are linked to decaying wood habitats.
Pyromorpha
orange-patched smoky moths, leaf-skeletonizer moths
Pyromorpha is a genus of zygaenid moths known as leaf-skeletonizer moths. Species in this genus possess aposematic black and orange coloration and contain hydrogen cyanide at all life stages, which they synthesize rather than sequester from host plants. The genus participates in Müllerian mimicry complexes with net-winged beetles (family Lycidae), particularly Calopteron terminale. At least one species, P. dimidiata, has larvae that feed on leaf litter, especially oak leaves.
Pyromorpha dimidiata
Orange-patched Smoky Moth
Pyromorpha dimidiata is a leaf skeletonizer moth in the family Zygaenidae, native to eastern North America. Adults display distinctive orange and dark gray forewings with a pattern that resembles toxic net-winged beetles (Calopteron spp.) in a Müllerian mimicry complex. All life stages contain hydrogen cyanide, which the moth synthesizes independently rather than sequestering from host plants. The species is active primarily in spring and early summer.
Virbia opella
tawny holomelina, Tawny Virbia Moth
Virbia opella is a small tiger moth in the family Erebidae, historically known as the tawny holomelina. It was described by Grote in 1863 and later transferred from Holomelina to Virbia following phylogenetic revision. The species occurs in eastern and central North America, where it inhabits oak-dominated forests and produces multiple generations annually.
