Cercidia prominens is a small orb-weaver spider (family Araneidae) known for its distinctive brick-red to orange coloration. Females measure 3.8–5.4 mm in body length, with males slightly smaller at 3.6–4.1 mm. The species was first described by Niklas Westring in 1851 and underwent several taxonomic revisions before receiving its current name from Tamerlan Thorell in 1869. It occupies a broad geographic range across the Northern Hemisphere.
Kaestneria pullata
Bog Sheet-web Weaver
Kaestneria pullata is a sheetweb spider in the family Linyphiidae, commonly known as the Bog Sheet-web Weaver. It has been documented across a broad geographic range spanning North America, Europe, and Asia, including Russia from European regions to the Far East, as well as China, Mongolia, and Japan. The species is one of approximately 4,600 described species in Linyphiidae, the second largest family of spiders.
Limnephilus externus
northern caddisfly
Limnephilus externus is a northern caddisfly species in the family Limnephilidae, first described by Hagen in 1861. The species has been documented in both North America and Europe. A detailed life history study in southern Alberta, Canada, revealed unique adaptations to temporary pool conditions, including egg-laying above water level and delayed larval entry into aquatic habitats. Adults emerge in August and exhibit a one-month reproductive delay.
Phryxe vulgaris
Phryxe vulgaris is a species of tachinid fly distributed across a broad geographic range spanning North America, Europe, and Asia. As a member of the family Tachinidae, it is a parasitoid fly, though specific host relationships for this species are not well documented in the available literature. The species was first described by Fallén in 1810 under the basionym Tachina vulgaris.
Walckenaeria auranticeps
Walckenaeria auranticeps is a species of dwarf spider in the family Linyphiidae. It was described by Emerton in 1882. The species has a transcontinental distribution spanning northern Eurasia and North America, with records from Russia (South Siberia to Far East), Canada, and the United States. As a member of the sheet-web weaving spiders, it belongs to one of the most species-rich families of spiders.
