Butterfly Sightings in Dutch Gardens Almost Double Despite Long-Term Decline

Butterfly sightings are on the rise in Dutch gardens, according to the latest report from the Dutch Butterfly Foundation. The annual garden butterfly count, which took place between July 11 and 13, saw over 15,000 garden and balcony observations submitted online. On average, participants reported seeing 9.8 butterflies per count, which is nearly double the average of recent years.

Experts caution that while this increase is a positive sign, there are still concerns about the overall decline in butterfly populations. Kars Veling, spokesperson for the Dutch Butterfly Foundation, noted that despite the improvement this year, we are still below half the number of butterflies observed thirty years ago. The goal is to reach the old average of 16 butterflies per count.

The atalanta butterfly was the most frequently spotted species this year, followed by the small white and the peacock butterfly. The results from the garden butterfly count were compared with data from the Meetnet Vlinders monitoring network in natural areas, confirming an overall improvement in butterfly populations in the Netherlands.

While some species, such as the small tortoiseshell butterfly, continue to decline due to factors like drought vulnerability, other species like the map butterfly are experiencing positive trends. Experts credit last year’s wet conditions for supporting these improvements but stress that long-term threats like drought, nitrogen pollution, intensive agriculture, and habitat fragmentation remain.

To help support butterfly populations, individuals can take action by planting native, flowering plants in their gardens and balconies, avoiding pesticide-treated plants, and choosing organic options whenever possible. By addressing these challenges at both policy and individual levels, we can work towards improving the numbers of these beautiful creatures in our gardens and natural spaces.
