Yorkshire Status: Very rare and very local resident.
Sutton & Beaumont, 1989: This species was not first taken in 1950, as previously stated (YNU, 1970), since this first specimen was from Totley in VC57 (Garland, 1979). However, the 1955 record was from Whirlow, VC63 and therefore is valid. There is one recent record which cannot now be verified.
2012 (CHF): The recent record referred to above was from the Rothamsted trap at Malham in 1971 and is still unconfirmed. We receive many reports of this species every year and almost invariably these turn out to be Double Square-spot. On 25.7.2011 however a genuine Triple-spotted Clay was trapped at Colt Park in the west of VC64 and verified by dissection. We may have a small resident population in this area as there are several records over the border in VC59 and 60. The old record from Malham now looks more likely.
