Euura poecilonota
Marbled Birch Nematine
Euura poecilonota is a species of sawfly in the family Tenthredinidae, commonly known as the Marbled Birch Nematine. It belongs to the large and diverse genus Euura, which comprises numerous species associated with willows and other woody plants. The species was originally described by Zaddach in 1876 under the name Nematus poecilonotus. Like other nematine sawflies, this species is likely associated with birch (Betula) as a host plant, though specific biological details remain poorly documented in available literature.
Euura robusta
Euura robusta is a species of sawfly in the family Tenthredinidae, subfamily Nematinae. Sawflies in this genus are typically associated with willow (Salix) species, on which larvae feed and induce gall formation. The genus Euura contains numerous species that are morphologically similar and often require specialist examination for accurate identification. As with other Nematinae, this species lacks the narrow waist characteristic of wasps and bees, instead showing a broad connection between thorax and abdomen.
Euura tibialis
Locust Sawfly, False Acacia Sawfly
Euura tibialis is a nematine sawfly in the family Tenthredinidae, commonly known as the locust sawfly or false acacia sawfly. The species is associated with false acacia (Robinia pseudoacacia) as its host plant and has been recorded from Korea, Canada, and parts of Europe including Denmark, Norway, and Sweden. It is one of numerous Euura species that specialize on particular host plants in the genus Robinia and related legumes.
