Neuroterus floccosus (Bassett, 1881), comb rev., sexual generation
Synonyms: Cynips floccosa Bassett (1881b: 111), asexual female, gall. Neuroterus floccosus combination by Mayr (1881: 37). Neuroterus verrucarum var. floccosus combination by Kinsey (1923: 70); combination of Mayr (1881) restored by Weld (1951: 621).
Neuroterus verrucarum var. pernotus Kinsey, 1923. Synonymized by Weld (1951: 621).
Melika & Abrahamson (1997) erroneously synonymized N. floccosus with N. quercusverrucarum.
Biology. See Bassett (1881b), Beutenmueller (1910), and Weld (1926) for the biology of the asexual generation. Asexual galls (Fig. 149) have been recorded on leaves of Q. bicolor and Q. macrocarpa. Galls become apparent in August as small depressions filled with loose, pale wool on the underside of new, terminal, long shoot leaves. Multiple galls often co-occur on a single leaf, which causes the leaf to curl, and galls tend to be found on stumps or damaged trees bearing vigorous, long late-season shoots. Adult females of the asexual generation emerge the spring following gall induction, from mid-April to late May. Galls of the sexual generation first appeared in late May on Q. macrocarpa in Edmonton, and adults emerged in late July and early August.
Distribution. USA: from Virginia west to Illinois (Burks 1979). Canada: Ontario (Burks 1979), Manitoba. This species was only reared in sleeves in Edmonton, Alberta, and does not naturally occur on bur oak there.
