The results of this year's Stocker's Lake annual Butterfly survey have now been published. Reflecting the national picture, our results show that the hot, dry summer produced a record year for sightings, especially during July and August, although there were notable further declines in some species.
When ranked by frequency of sighting at the lake the Whites occupy 3 of the top 5 places in 2018 while Holly Blue and Ringlet also increased. Red Admiral, though, has fallen from 3rd place in 2012, to 7th in 2017 and 14th in 2018. Small Tortoiseshell has similarly suffered a fall in ranking, and an even larger decline in numbers counted. Overall though the number of butterflies counted this year was 36% higher than in 2017, and 3% higher than our previous record in 1997.
