Dorcus parallelipipedus, the lesser stag beetle, is a species of stag beetle found in Europe. Both sexes resemble the female greater stag beetle (Lucanus cervus), though they are a uniformly blackish colour rather than having the chestnut brown wing covers (elytra) of the larger species. Males have distinctly knobbed antennae, and although their jaws are somewhat larger than those of the females, they are nowhere near as large as those of many other male stag beetles. The lesser stag beetle is similar in appearance to the related antelope beetle (Dorcus parallelus) of North America. Adults are from 18 to 32 mm (0.7 to 1.3 in) in length.
Like those of other stag beetles, the white, C-shaped larvae feed on wood. Adults as well as larvae are found in very soft decaying wood of broad-leaved trees, especially ash (Fraxinus excelsior), beech (Fagus sylvatica) and apple (Malus spp). Adults cannot eat solid food, but they can drink tree sap and the liquid of fallen fruits.
Adult beetles can be found in woodland, parkland and hedgerows in the summer, often resting in the sun on trees. After they mate, females lay their eggs in rotting... Wikipedia →

Possible
About 30% of wildlife watchers report a Lesser Stag Beetle sighting in Kyiv on a given day, based on 307 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 753 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report a Lesser Stag Beetle in Kyiv on a given day, against under 5% in November to February, the lowest months. That is one of Kyiv's wettest months, with about 75 mm of rain against 40 mm in April.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Lesser Stag Beetle sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 27 cities where we can rate Lesser Stag Beetle sightings, Kyiv has the highest daily chance: about 30%. Next come Kharkiv (Ukraine, about 30%) and Essen (Germany, about 30%).
GBIF citizen-science records
It is estimated from how often the Lesser Stag Beetle is recorded against all the insects logged in Kyiv (307 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.
