Like some other wet grassland sites there can be considerable variations in counts over the 14 years but overall the trend is slightly upwards at about  5% per decade mostly due to slight increases in  Meadow Brown and Ringlet who's ups and downs dominate the annual totals. Other species show a small decline such as Small Skipper and Large Skipper down alot. Most species show the 2013 and 2019 peaks and the duldrums of 2009 and 2011 period reflecting wider countryside trends at this time.  

As in the Vale of York it has seen dispersing Marbled Whites in the recent boom years 2020-22.

 Wall  disaapeared at the same time as most areas in 2007-8 very wet summers.

Total count in 2021  was high 22% above the 5 year average and close to teh 2019 exceptionally good year which is against the trend of other transects being mostly down at least a few percent. The reason is mostly a very high count of Meadow Brown.   It far from all good news as with other transects the skippers were well down as were the cabbage whites  Small Copper and Common Blue. The Vanessids  were all down apart from Small Tortoiseshell which continues to boom on nearly all transects. Also reflecting other transects Gatekeeper and Orange Tip  are up.  It was great that Marbled White visited again but they are also had a good year on the wolds.  

Highlight of the year was sighting of a Marbled White.  However numbers of other species were well down this year in particular Common Blue, Brown Argus, Small Copper but particularly Holy Blue. The skippers also suffered and we might guess this all relates to last year heat and this years drought.  Ringlet was also down which has been a pattern this year.   However the Vannesids were definately up particularly Small Tortoiseshells and the migrant Red Admiral and Large White showed very well.
