Yorkshire Status: Uncommon and local resident.
This species has been recorded a lot more frequently in recent years. It is difficult to know how much of this is due to better awareness and now much is a genuine increase in numbers, though the Atlas implies that nationally the range has expanded, and there have now been records in Scotland. This is another very small species and can be mistaken for Slender Pug by the unwary as it flies at a similar time, peaking in the first week of August. Its wings are not quite as rounded as Slender Pug and it shows little in the way of a discal spot. Worn specimens or those from new sites may need dissection. Like may Pugs, a good way to find it is by dusking around its foodplant (field maple) though others have had considerable success beating old maple flowers on mature trees in May.
Sutton & Beaumont, 1989: There are now six known sites in Yorkshire for this species and there may well be more as it is very easy to overlook (AMR pers. comm.). Recorded in 62 (31%) of 200 10k Squares. First Recorded in 1876. Last Recorded in 2024. Additional Stats |
