Biology. This is an abundant upland species in Europe not distinguished from F. fuscaHNS until Bondroit (1917) and first clearly described by Yarrow (1954). It has similar habits to F. fuscaHNS but sometimes occurs in large multi-queened colonies in favourable sites such as stony banks. Colony founding is either by single queens or by nest fission. Alatae fly in July and August.
