The Bellenden Ker Scaly Snail (Aetholitis gerdesae) is a species in the genus Aetholitis. It is currently classified as Least Concern on the IUCN Red List. Typically found in terrestrial and aquatic habitats including forests and freshwater.

Common Ectemnius

<em>Ectemnius continuus</em>, the common ectemnius, is a solitary predatory wasp in the family Crabronidae, classified as Least Concern by the IUCN Red List. The species is documented in Belgium, Denmark, Norway, Sweden, and the United States, occurring across virtually all terrestrial and freshwater biome types within its range. <em>Ectemnius continuus</em> is a wood-nesting wasp that typically excavates nest galleries in dead or decaying wood, including logs, stumps, and structural timber, where females provision individual brood cells with paralyzed flies as larval food. The adult wasps are diurnal and can often be observed at flowers, consuming nectar as a fuel source, or hunting flies in sunlit forest edges, hedgerows, and gardens. Females are capable hunters, pursuing and paralyzing dipteran prey in flight before carrying them back to the nest. As predators of flies, crabronid wasps like <em>Ectemnius continuus</em> contribute to the natural regulation of fly populations in temperate ecosystems. The species is part of a diverse guild of cavity-nesting aculeate hymenoptera that occupies dead wood habitats, making dead wood retention in forests ecologically important for their conservation. Biological traits of this species remain poorly documented in the scientific literature.
