Juniper : Juniper tip midge
(revision date: 4/23/2014)


Biology
Juniper tip midge larvae feed in the tips of shoots, causing them to swell and form green galls. After the larvae have left, the galls turn brown (sometimes reddish) and the tips die back. Symptoms of mining and exit holes may be found at the junction between living and dead tissue or at the base of the swollen portion.
