Tenthredo scrophulariae, the figwort sawfly, is a species of the family Tenthredinidae, subfamily Tenthredininae. This species is widespread across Europe, Turkey and Transcaucasia, in meadows wherever figwort grows. Tenthredo scrophulariae can reach a body length of approximately 11–15 millimetres (0.43–0.59 in). It is easily recognisable by its wasp-like appearance although lacking the thin 'waist' of a true wasp. The head is black and quite short, with prominent, rectangular back corners. The flagellum of the antennae is not narrowed on the tip, it is quite short (less than twice as long as the head width) compared to many related species. It is orange colored, while in most similar species of the genus it is black. The thorax is predominantly black, only the pronotum and scutellum are yellow. The abdomen is black, with transverse bands of yellow.
The leading edge of the forewings, including the veins, is intense orange-red colored, while the remaining wing-membrane is transparent pale yellowish, gray tinted towards the tip. The front legs are almost completely yellow, but the upper sides of the femurs are black. The middle and the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Figwort Sawfly sighting in Brussels on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 337 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and July–September
In those months about 10% of wildlife watchers report a Figwort Sawfly in Brussels on a given day, against under 5% in June and October–April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Figwort Sawfly sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 7
Of the 7 cities where we can rate Figwort Sawfly sightings, Brussels ranks 2nd at under 5%. The best odds are in Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Figwort Sawfly is recorded against all the insects logged in Brussels (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
