The galls of Neuroterus numismalis parthenogenetic generation on Quercus robur leaf. Neuroterus is a genus of gall wasps that induce galls on oaks in which the wasp larvae live and feed. Some species produce galls that fall off the host plant and 'jump' along the ground due to the movement of the larvae within.
Neuroterus albipes is a gall wasp that forms chemically induced leaf galls on oak trees which has both bisexual and agamic generations and therefore forms two distinct galls, the smooth spangle gall and Schenck's gall. [1] Neuroterus laeviusculus and Spathegaster albipes are previous binomials found in the literature. [1]
Jumping oak galls are caused by a very tiny, native, stingless wasp (Neuroterus sp.) which lays eggs in leaf buds. As the leaf develops, pinhead-sized galls, also referred to as abnormal plant ...
The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
Neuroterus numismalis is a gall wasp that forms chemically induced leaf galls on oak trees. It has both bisexual and agamic (parthenogenetic) generations and forms two distinct galls on oak leaves, the silk button gall and blister gall. The galls can be very numerous with more than a thousand per leaf. [1]
The all-female generation's galls appear in late spring. These round, 1 mm across galls occur on the underside of leaves, and eventually detach and fall into the leaf litter. Adults emerge early the following spring and lay eggs for the bisexual generation. This generation induces galls that are integral to the leaf. [2] [1] Adult wasps are .75 ...
