Pineapple Gall Adelgid - Adelges abietis
The Pineapple Gall Adelgid (Adelges abietis) is a type of conifer-feeding insect, similar to an aphid that forms pineapple-shaped plant galls on its host species, commonly Norway and Sitka spruce. The galls are more noticeable than the insect. The mature gall is ellipsoidal with its length less than 1.5 times the width and usually about 15 to 20 mm in length. The spruce needles on the gall are shorter than normal. The gall is only slightly paler green than a normal shoot. The slits to gall chambers are often orange-red or deep pink before opening. There are often several galls together at the base of adjacent shoots, and plant growth often continues beyond gall.
In areas where Norway and Sitka Spruce are present.
Galls are present in summer with the gall chambers opening in August or September.
Status in Britain is difficult to determine due to lack of records.
Status in Leicestershire and Rutland not known.
