Zygaena trifolii, the five-spot burnet, is a day-flying moth in the family Zygaenidae found in North Africa and Europe. It was described by the German zoologist Eugenius Johann Christoph Esper in 1783 from the type specimen found in Frankfurt am Main, Germany.
The wingspan is 28–33 mm. Adults are on wing from the mid-June to the beginning of August in one generation per year. Ovum Eggs are pale yellow and deposited in several layers to form an irregularly shaped batch. Larvae The larvae feed on the leaves of greater bird's-foot trefoil (Lotus uliginosus) and bird's-foot trefoil (Lotus corniculatus). The species overwinters in the larval stage and may overwinter twice.
Pupa The pupa is shiny, black or blackish-brown and 10–18 mm long. Pupation of subsp descreta takes place in June and July in a cocoon which is spun high on marsh vegetation such as soft rush (Juncus effusus). Pupation of subsp palustrella takes place close to the ground and concealed amongst grass and other herbage in late-April to May. The cocoon is fusiform, irregularly ribbed and ranges from dirty white to creamy-white to bright yellow.

Rare
Under 5% of wildlife watchers report a Five-Spot Burnet sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Five-Spot Burnet in London on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Five-Spot Burnet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Five-Spot Burnet sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Porto (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Five-Spot Burnet is recorded against all the insects logged in London (6 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.
