Where are all the Butterflies?
Butterfly Conservation reports a significant decline in butterfly numbers during this year's Big Butterfly Count, attributed to adverse weather and long-term habitat loss, urging public participation for conservation data.

Butterfly Conservation has reported significantly low numbers of butterflies during this year's Big Butterfly Count, with participants observing just over half the number compared to the same period last year. The decline is attributed to unusually wet and windy weather in spring and cooler summer temperatures, which hinder butterflies' ability to fly and breed. This year's count is on track to record the lowest numbers in the event's 14-year history. Dr. Dan Hoare, Director of Conservation, emphasized that butterflies require warm and dry conditions for mating and breeding, and the current weather conditions are detrimental.
Additionally, the charity highlighted that the decline in butterfly populations is not solely due to this year's weather; since the 1970s, 80% of UK butterfly species have decreased, primarily due to habitat loss, climate change, and pesticide use. The lack of butterflies serves as a warning sign for the overall health of the environment.
Butterfly Conservation urges the public to participate in the Big Butterfly Count by spending 15 minutes outdoors to record butterfly sightings, regardless of the number seen. This citizen-science initiative is crucial for gathering data that informs conservation efforts and policy decisions. The count runs until August 4, and participants can join through the website or a dedicated app. Last year, over 135,000 counts were recorded, contributing valuable information for scientific research and conservation strategies.
