Elampini
Elampini is a tribe of cuckoo wasps within the family Chrysididae, comprising approximately 12 genera including Elampus, Hedychrum, and Holopyga. Members are kleptoparasitic wasps that lay eggs in the nests of other hymenopterans, particularly solitary bees and wasps. The tribe is distinguished by morphological features of the metasoma and male genitalia. Elampini species are found across the Holarctic region with highest diversity in the Palearctic.

Elasmini
Elasmini is a historical subfamily name in the family Eulophidae (Hymenoptera: Chalcidoidea), erected by Förster in 1856. It is currently treated as a synonym and is no longer recognized as a valid taxonomic rank within Eulophidae. The name reflects early attempts to subdivide the diverse eulophid wasps based on morphological groupings that subsequent research has not supported as monophyletic.

Empria coryli
Empria coryli is a species of sawfly in the family Tenthredinidae, first described by Dyar in 1897. The species epithet "coryli" suggests a potential association with Corylus (hazelnut), though this relationship has not been confirmed in the available literature. Records indicate occurrence in Quebec, Canada. As with other Empria species, it likely exhibits the typical sawfly characteristic of herbivorous larval feeding on plant foliage, but specific biological details remain poorly documented.

Endelomyia aethiops
roseslug, rose slug sawfly, roseslug sawfly
Endelomyia aethiops, commonly known as the roseslug or rose slug sawfly, is a species of common sawfly in the family Tenthredinidae. The larvae are significant pests of cultivated roses, causing characteristic skeletonization damage by feeding on leaf tissue between vascular bundles. Adults are small, wasp-like insects that emerge in spring to lay eggs on rose foliage. The species has a single generation per year in most regions, with larvae active primarily in May and June.
