Melikaiella flora, formerly Callirhytis milleri, the live oak petiole gall wasp, is a species of hymenopteran that produces leaf galls on coast live oak, interior live oak, and canyon live oak trees in California in North America. [1] [2] The gall often subsumes the entire petiole and occasionally part of the leaf body. [1]
Amphibolips quercuspomiformis, also known as the apple gall wasp or live oak apple gall wasp, is a species of gall wasp. It induces galls in coast live oak and interior live oak trees. Like many gall wasps, it has two alternating generations which induce differing galls: an all-female parthenogenic generation, and a bisexual generation. The ...
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 ...
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 ...
An oak apple or oak gall is a large, round, vaguely apple-like gall commonly found on many species of oak. Oak apples range in size from 2 to 4 centimetres (1 to 2 in) in diameter and are caused by chemicals injected by the larva of certain kinds of gall wasp in the family Cynipidae .
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]
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]
Atrusca capronae, also known as the striped oak-apple gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in North America. [1] The wasp oviposits on shrub live oak leaves. [1] The intensity of the stripe color may vary regionally. [1]
