Carpatolechia fugitivella
elm groundling
Carpatolechia fugitivella, commonly known as the elm groundling, is a small gelechiid moth with a wingspan of 11–15 mm. The species is widespread across Europe, extending into Asia and North America. Adults are active from June to September and are attracted to light.
Eutrichota
root maggot fly
Eutrichota is a genus of true flies in the family Anthomyiidae, established by Kowarz in 1893. Members are commonly referred to as root maggot flies, reflecting their larval association with plant roots. The genus occurs across northern Europe and North America, with over 6,000 observations documented on iNaturalist. Like other anthomyiids, these flies are generally small to medium-sized with dull coloration.
Oulema
Cereal leaf beetles
Oulema is a genus of leaf beetles in the family Chrysomelidae, subfamily Criocerinae. The genus contains approximately 100 species distributed primarily in temperate to tropical regions. Several species are economically important agricultural pests, most notably Oulema melanopus (cereal leaf beetle), which has been introduced to North America and causes significant damage to wheat and other small grain crops. The genus can be distinguished from the closely related Lema by pronotum shape and the converging angle of frontal grooves.
Quediina
Quediina is a mega-diverse subtribe of rove beetles (Staphylinidae: Staphylinini) comprising hundreds of species globally, with exceptional species richness in north and south temperate regions. The subtribe has historically been defined by convention rather than clear synapomorphies, and recent phylogenetic studies have demonstrated polyphyly, leading to major taxonomic revisions. Formerly quediine genera from the Afrotropical region have been reassigned to unrelated lineages within Staphylinini. The subtribe includes economically important genera such as Quedius and Bolitogyrus.
Rhyzobius
Rhyzobius is a genus of small lady beetles (Coccinellidae) in the tribe Coccidulini. The genus was established by J.F. Stephens in 1829 (published 1832) and contains approximately 106 recognized species worldwide. Members are specialized predators of scale insects (Coccoidea), particularly armored scales (Diaspididae). Several species, notably R. lophanthae and R. ventralis, have been widely introduced as biological control agents against scale pests in temperate regions globally.
Strongylogaster
Strongylogaster is a genus of sawflies in the family Tenthredinidae. Members are found in Europe and North America. The genus contains multiple species, though many remain poorly documented. Sawflies in this group are phytophagous as larvae.
Yponomeutoidea
Ermine Moths and Allies
Yponomeutoidea is a superfamily of Lepidoptera comprising approximately 1,800 species worldwide, predominantly distributed in temperate regions. The group includes eleven families: Argyresthiidae, Attevidae, Bedelliidae, Glyphipterigidae, Heliodinidae, Lyonetiidae, Plutellidae, Praydidae, Scythropiidae, Yponomeutidae, and Ypsolophidae. Yponomeutoidea represents one of the earliest lepidopteran lineages to evolve external feeding on foliage and to colonize herbaceous plants in addition to woody shrubs and trees. Larval habits are diverse, including leaf-mining, external feeding, and boring behaviors, with many species exhibiting specialized host plant associations.
