After last year’s wet summer and this year’s cold spring, it was touch and go for many butterfly species. However, the hot, dry weather at the beginning of July was a turning point for many, including the Small Tortoiseshell. Although their numbers normally increase at the end of the summer, with new butterflies emerging from the second brood, the BTO’s Garden BirdWatch reporting rate exceeded expectations for the time of year, and was double that seen the same time last year.
