Neuroterus albipes
''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.〔Darlington, Page 162〕 ''Neuroterus laeviusculus'' and ''Spathegaster albipes'' are previous binomials found in the literature.〔
==Galls==
The normally cream coloured saucer of the smooth spangle gall has a small cone elevated in its centre, a pronounced rim and they are sometimes found almost folded in two.〔 The gall may have streaks of purple, red or other colours through it. Typically found on the lower surface, this gall is found more often on the upper surface than other spangle galls and although often grouped together, the numbers on each leaf are far fewer than in species such as ''Neuroterus quercusbaccarum''. The gall is observed to swell appreciably once it has detached and fallen in late autumn. The gall has also been recorded as green, purple, red or pink.〔
Schenck's gall is an oval shaped structure, about 0.1 × 0.2 cm and a light green colour, well camouflaged with the leaf lamina. A distinct indentation of the lamina margin is apparent through the inhibition of the normal growth of the leaf by the developing gall; the gall may also appear on the midrib.〔〔Stubbs, Page 48〕
Both galls are both unilocular and unilarval.〔
