Oestrus trompe Modeer, 1786 Cephenemyia trompe,[1] also known as the reindeer nose botfly, is a species of botfly first described by Adolph Modéer in 1786.

It belongs to the deer botfly genus Cephenemyia.

[1][3] The larvae of Cephenemyia trompe infect the nose area of reindeer.

[4] The adult is active during the Arctic summer, being able to fly very fast and having developed olfactory abilities to find reindeer from long distances.

[5] Its activity, however, is inhibited by strong winds, low temperatures and rain or snow.
