For the county, we have a total of 24 records from 9 sites. First recorded in 1876.
Sutton & Beaumont, 1989: This species still occurs at its famous site near Grassington (VC64), the most recent records being 10.8.1983 (SMJ, MRB) and 10.8.1987 (SMJ, JW). This is the only known Yorkshire location for this species, although there has been an unconfirmed report from VC62.
2012 (CHF): Porritt noted this species on Malham Moor and near Oughtershaw in upper Wharfedale. It was recorded again from Oughtershaw in 1967. It has been recorded from the Grass Wood area for many years but not since 1987. It turned up regularly in the Colt Park RIS trap from 1990 to 1993 ie during the whole time the trap was operated, but limited trapping at this site since then has not found it. It is hoped to trap more regularly here. Does this species still occur in Yorkshire or is it moving north because of climatic change?
I have located the "unconfirmed report from VC62" from The Naturalist in 1891. These old reports always make good reading and this one is as follows:
"Larentia ruficinctata near Scarborough - I beg to record the finding of the imago of Larentia ruficinctata on Hutton Buscel Moor on July 16th. I was in the company of Mr H.W. Head who at once identified the insect, which tallies exactly with the description in Newman. It differs materially from L. caesiata which is, I believe, not uncommon here. The moor at that point is about 450 feet above sea level. The White Meadow Saxifrage (S. granulata) does not grow in the neighbourhood, and therefore as this is the only food-plant named by Newman, the larva probably has alternative food-plants not yet recorded. Reginald H. Barker, Hull, August 7th 1891." According to Waring, this species feeds on Saxifraga hypnoides (mossy saxifrage) in Yorkshire and this has apparently never been native to VC62, so it it difficult to know what to make of this record.
