Description

The main picture shows a dissected gall exposing larvae at various stages of development with pale pink segmented bodies and a few eggs (pic 4). The galls were about 3 to 4 mm wide, shiny and green with knobbly tips. They seemed to arise from tips of leaflets (pinnules) and involved most of the leaflet (pic 2). Several of these galls were seen on the pinnae. Pic 4 shows a developing gall on a leaflet. The larvae seemed to have segments differentiated into thoracic and abdominal segments and there appeared to be three pairs of legs (pic 6) suggesting that these were mature and close to pupation ?. I assume these are midge galls and would greatly appreciate confirmation.
