The average number of peacock butterflies seen by participants in the count fell by 42% compared to last year.
If you think you saw fewer butterflies than ever this British summer, you are probably correct: the Big Butterfly Count has recorded its lowest number of common species since records began.
Normally ubiquitous butterflies such as the gatekeeper, comma and small copper experienced their worst summers in the history of the count, which is run by Butterfly Conservation and began in 2010.
Scientists said the low number of butterflies is "a shock and a mystery" because this summer was warmer than average and much drier in England than the previous worst year for butterflies, 2012, which was unusually cold and wet.
"The drop in butterfly numbers this summer has been a shock," said Richard Fox of Butterfly Conservation. "When we have cold, wet summers, as in 2012, we expect butterfly populations to plummet, but that wasn't the case this year.
