Anastrangalia sanguinolenta, the blood-red longhorn beetle, is a species of flower longhorn beetles belonging to the family Cerambycidae, subfamily Lepturinae. This beetle is a common species present in most of Europe and in the Near Eastern countries such as Caucasus, Transcaucasia, and Turkey, where they mainly inhabit mountainous coniferous forests.
Head, antennae and pronotum are black in both sexes, while elytra are reddish-brown in the female and yellowish-brown in the male. The adults grow up to 8–13 millimetres (0.31–0.51 in) and can be encountered from May through August, completing their life cycle in 2–3 years.
The larvae develop at the expense of various species of conifers, mainly within dead wood of Pinus sylvestris and Picea abies. The adults visit flowers for nectar and pollen. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blood-Red Longhorn Beetle is recorded against all the insects logged in Pyrénées National Park (34 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.
