Andricus lucidus

Gall wasp Andricus lucidus

Description

The spiky asexual gall is only about 3-4 mm in diameter, but from it are developed 6-7 mm long outgrowths thickened at the end. That makes it optically bigger. Inside each gall develop more larvae. It often occurs in groups on young oaks. It is not very common, commoner is only in warmer steppe localities. In the places of occurrence it can appear massively. The adult hatch in spring. A sexual gall looks rather different. The asexual galls can block buds on younger trees, but rarely abundant enough to cause significant damage. It prefers young oak stands.
