East Atlantic teleconnection pattern and the decline of a common arctiid moth

Teleconnection patterns are large-scale atmospheric circulation systems and variation in them is often associated with impacts on climate and weather over broad areas. Arctia caja L. is a well-known, widespread and charismatic tiger moth. In recent decades, the abundance of A. caja in UK has fallen...
