Stictoleptura rubra, the red-brown longhorn beetle, is a species of beetle belonging to the family Cerambycidae. They visit flowering plants for nectar and pollen, while larvae develop and feed within dead wood and tree stumps of coniferous trees (Picea, Pinus, Abies, Larix). They have yeasts in their gut, enabling them to digest cellulose.
Stictoleptura rubra can reach a length of 10–20 millimetres (0.39–0.79 in). This species has an evident sexual dimorphism, with variations in color and shape. Elytra and pronotum of the females are uniformly reddish-brown or reddish-orange, while in males head and pronotum are black. Moreover the males have brown or pale ochre elytra and often they are smaller and narrower than the females.

Likely
About 40% of wildlife watchers report a Red Pine Longhorn Beetle sighting in Tatra National Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 142 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Red Pine Longhorn Beetle in Tatra National Park on a given day, against under 5% in March–June and October–December, the lowest months.

GBIF citizen-science records
It is estimated from how often the Red Pine Longhorn Beetle is recorded against all the insects logged in Tatra National Park (56 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.
