Great Capricorn Beetle

Dear Andrew,
This is a Longicorn in the family Cerambycidae, and based on images posted to Beetles from Romania, we originally thought it might be
Monochamus sartor, a member of the genus commonly called Sawyers, but additional research has caused us to rethink that and to conclude that it is more likely a Great Capricorn Beetle, Cerambyx cerdo, a mistake we have made in the past.  The images on iNaturalist were a strong factor in our correction.  According to a pdf from EU Wildlife and Sustainable Farming Project:  “The great capricorn beetle is a large beetle with a thin body and very long antennae which are longer than the body” and “The species is declining across Northern Europe but is still relatively common in South France, Spain and Italy. Nevertheless, even here, the rate of decline is worrying.”
