Yorkshire Status: Uncommon and fairly widespread resident.

The 2020 lockdown ramblings give a pretty good summary of this species in the county and paint a more pessimistic picture than Sutton and Beaumont's summary. Numbers however may have stabilised in the last few years.

2020 (CHF): Tawny Speckled Pug is one of the easiest Pugs to identify and is always a pleasure to find in the moth trap. It is however in trouble. It has been in decline for many years. For the very first time this year there were no records at all in VC64. There was only one site in VC63. The situation is mirrored to a certain extent nationally though I get the impression that it is not doing quite as badly in the south and east of the country. It occurs in a variety of habitats and the main food plant is said to be yarrow, but I think it is commonest in calcareous herb-rich weedy areas. I think the most likely cause of the demise is our obsessive drive to 'tidy up' our countryside, cut our road verges too early, build 'affordable housing' on brownfield sites and plough up to the edges of our fields. Its closest relative, Bordered Pug, another attractive and easily-recognised species, is in the same predicament. Its larvae feed on Mugwort and Wormwood and it is even more a species of disturbed ground. Numbers are slowly dropping and insidious 'tidying up' is again likely to be the reason.

Sutton & Beaumont, 1989: Widely distributed and locally common where yarrow is plentiful in all five vice-counties. This species is recorded more frequently than many other pugs, perhaps because it is relatively easy to identify.
