Common Flat-body

<em>Agonopterix heracliana</em> is a moth belonging to the family Depressariidae within the order Lepidoptera. Commonly known as the common flat-body, this species is named for the flattened resting posture characteristic of the genus Agonopterix. The species is classified as Least Concern on the IUCN Red List, with no indication of significant population decline. <em>Agonopterix heracliana</em> is distributed across northwestern Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden. Larvae of this species are typically associated with plants in the family Apiaceae, particularly hogweed (Heracleum sphondylium) and related umbellifers, upon which they feed while sheltering in rolled or folded leaves. Adults are typically brownish with subtle markings and are active from late summer through winter and early spring, overwintering as adults — an unusual life history trait among moths. The species inhabits hedgerows, woodland margins, and meadows where its host plants are abundant. Biological traits of this species remain poorly documented in the scientific literature.

Common Jelly Spot

<em>Dacrymyces stillatus</em>, commonly known as the common jelly spot, is a saprotrophic fungus in the family Dacrymycetaceae. It is classified as Least Concern on the IUCN Red List, with records from five European countries and North America. The species typically grows on damp, dead, or decaying wood, particularly coniferous timber, forming small, gelatinous, orange-yellow cushions or pustules on the substrate surface. As a saprotrophic wood-decay fungus, it contributes to nutrient cycling and the decomposition of woody material in temperate forest ecosystems. The bright gelatinous fruiting bodies make it a conspicuous species when encountered on wet wood in cool, humid conditions. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
