Distribution and habitat
This rather common species is present in most of Europe and in the eastern Palearctic realm. These wasps mainly inhabit meadows, hedge rows, damp places close to streams, and man-made environments.
Description
Adults of Symmorphus gracilis can reach a length of 7–10 millimetres (0.28–0.39 in) in males, of 8–12 millimetres (0.31–0.47 in) in females. These slender tube-nesting wasps have a black head and furrows on the black thorax. On T1 there are a transverse hull and a median longitudinal groove. The small scales at the base of the forewings are black with a yellow border. Antennae of the males are straight up to the end. In the females there are dimples behind the posterior ocelli.
Biology
Adults can be found from June to August.
The public source identifies “Symmorphus gracilis” as species of insect. This brief keeps that definition visible, then builds a research path around Symmorphus, gracilis and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Symmorphus gracilis”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q14395984. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1832 and 1963.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
