In line with the group, Scottish data of oil beetles on iRecord greater than doubled final yr as a result of mixed effort of the Scottish Oil Beetle Hunt and surveying carried out by the Species on the Edge staff. Survey work for Quick-necked Oil Beetle specifically yielded over 100 data of particular person beetles, with many new websites found for the species. The Black Oil Beetle was additionally confirmed from Scotland, following doubt about earlier data because of points with misidentification.

In 2023, Quick-necked Oil Beetle had been discovered on Tiree for the primary time by Ranger Hayley Douglas. Lengthy regarded as current, this discovery is the most recent new island website for the species, following on from populations present in North Uist in 2022, and Barra and Islay in 2021.

Utilizing specialised hooks on their toes, they connect themselves to the again of a visiting feminine bee and when the bee returns to its underground nest, the triungulin disembarks and continues its growth underground, consuming via the bee’s shops of pollen and nectar. Relying on species, they then emerge in the identical or following yr, as an grownup oil beetle prepared to begin the life cycle once more.
