Contents

Rabdophaga jaapi is a species of gall midges which forms galls on creeping willow ( Salix repens ).

Description

The gall is an enlarged bud on S. repens. It is surrounded with small thickened leaves which have short silver-white hairs. [1] Correct identification of the species of Salix is important for the identification of R. jaapi, because it is similar to R. rosariella, which forms galls on sallows. [a] The gall of R. jaapi can also be positively identified by the single reddish-yellow larva which has a sternal spatula, i.e. ″... a structure on the underside of the thorax of the final (third) instar larva of Cecidomyiidae...″. [1] [2]

The species has one generation a year (i.e. univoltine) and the larva hibernates in the gall where it pupates. [3]

Distribution

Has been found in Denmark and Great Britain.

Notes

  1. ↑ In this case sallow refers to S. aurita, S. caprea and S. cinerea.
