More studies have been released highlighting how neonicotinoids affect bee populations as well as butterflies.
For years now, the agrochemical companies responsible for manufacturing neonicotinoids, have defended their products, in the face of substantial independent field and laboratory research highlighting the dangers of these widely used pesticides, to bees and other pollinators.
The World Wide Integrated Assessment of the Impact of Systemic Pesticides on Biodiversity and Ecosystems has made a synthesis of 1,121 published peer-reviewed studies , and the EFSA recommended restrictions to the use of some of these chemicals.

Some years ago I highlighted the fact that some patents for products containing neonicotinoids indicate that the product can be used to “control” non-target insects such as Lepidoptera (i.e. butterfly and moth) species.
To my mind it seems obvious therefore, that
such data within patents should be taken into account when assessing applications
to register them.......
........whilst also taking account of the fact that manufacturers may be reluctant to mention on a patent whether a product is lethal to bees (because a product posing “unacceptable risk” to bees cannot legally be approved), whereas it is safe for pesticide manufacturers to admit killing a close relative – i.e. Vespa (wasp) species without risk of their application to register the pesticide being overturned.
Two recent papers outline the effects of neonicotinoids
on butterflies, and it’s not good news – hardly a surprise! See previous article about UK butterfly decline.

In the UK, in a joint study completed by Sussex and Stirling Universities, researchers found population trends of 15 species showed declines associated with neonicotinoid use, including Small Tortoiseshell, Small Skipper and Wall species. The study is based on data gathered from more than 1000 sites across the UK as part of the long-running UK Butterfly Monitoring Scheme.
