Clytra laeviuscula, the ant bag beetle, is a species of short-horned leaf beetles belonging to the family Chrysomelidae, subfamily Cryptocephalinae. They are found in most of Europe, in the eastern part of the Palearctic realm, and in the Near East.
These beetles inhabit wet forests, sunny forest edges, dry slopes and dry grasslands, but also floodplains and parks. Clytra laeviuscula can reach a length of 7.5–11.5 millimetres (0.30–0.45 in) and a width of about 4 millimetres (0.16 in). These beetles have elongated bodies and shiny red-orange elytra with four black spots, two larger around the center of the elytra and two smaller on the shoulders. The prothorax is black and shiny. The head and legs are black, as well as the antennae that are quite short.
Clytra laeviuscula can be distinguished from ladybirds (family Coccinellidae) by its more elongated form and by its tarsi (ends of the legs) formed of five parts (three for ladybugs). This species is rather similar to Clytra quadripunctata.
Adults occurs frequently from May to August. They are phytophagous. They feed on leaves, flowers and pollen of deciduous trees, mainly... Wikipedia →

With luck
About 10% of wildlife watchers report a Willow Clytra sighting in Berlin on a given day, based on 131 verified sightings from GBIF citizen-science data. It is the 58th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Willow Clytra in Berlin on a given day, against under 5% in August to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Willow Clytra sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 11 cities where we can rate Willow Clytra sightings, Berlin ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%).

GBIF citizen-science records
It is estimated from how often the Willow Clytra is recorded against all the insects logged in Berlin (131 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.
