Oedemera nobilis, also known as the false oil beetle, thick-legged flower beetle or swollen-thighed beetle, is a beetle in the family Oedemeridae, a common species in Western Europe, including south and central England. The male of Oedemera nobilis, as in most Oedemera species, possesses hind femora that are very swollen, whereas in the female the femora are thin; the elytra are strongly narrowed towards the apexes, not hiding the membranous hind wings. It is bright green, frequently with a golden or coppery shine; some individuals are blue or violaceous. It can only be confused with Oedemera flavipes (which does not live in the British Isles), from which it differs by its colour, as well as by the long white pubescence on the head, pronotum and hind tibiae of males.
Oedemera nobilis is abundant in spring on several flower species; the males are very conspicuous by their swollen femora and bright green colour. It feeds on pollen and nectar of Asteraceae, Cyperaceae, Convolvulaceae, Cruciferae, Dipsacaceae, Scrophulariaceae, Poaceae, Papaveraceae, Plantaginaceae, Rosaceae, Rubiaceae and Apiaceae. The larvae develop on dry stems of Spartium and... Wikipedia →

Possible
About 20% of wildlife watchers report a Thick-Legged Flower Beetle sighting in Snowdonia National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 387 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and June
In those months about 40% of wildlife watchers report a Thick-Legged Flower Beetle in Snowdonia National Park on a given day, against under 5% in September to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Thick-Legged Flower Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 parks where we can rate Thick-Legged Flower Beetle sightings, Snowdonia National Park has the highest daily chance: about 20%. Next come Picos de Europa National Park (Spain, about 20%) and Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Thick-Legged Flower Beetle is recorded against all the insects logged in Snowdonia National Park (41 verified sightings from 2019 to 2026), 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.
