Andricus curvator
Andricus curvator is a Cynipid gall wasp that causes galls to form in the leaves of Oak.
The sexual generation gall is more often recorded in oak leaves or occasionally in a twig; rarely in catkins. In the leaf, it is roughly globular, about 8 mm across and often distorts the leaf and midrib; sometimes several galls coalesce. In a twig, it causes a swelling and usually a bend in the twig, with a spherical inner gall.
The asexual gall is in a bud, and is ovoid or pip shaped, smooth and greenish with a white ring behind the tip at first.
The sexual galls of Andricus inflator are also in a twig, but with a long and narrow interior cavity; to record these two galls the gall needs to be opened.
Where Oak is present.
June and July.
Widespread and fairly frequent in Britain.
Status in Leicestershire and Rutland not known.
