Life cycle - Adelges abietis - Female
Repentigny, Lanaudière County, Quebec, Canada
September 26, 2011
Sometimes the dead adult falls down, exposing the eggs. Here, half of them have hatched. They stayed together a few days. Each of them is a fundatrix which will overwinter and induce its own gall the following spring. The mortality rate is very high.
