Habits and Life History:
Cherry bark totrix is commonly found in the bark of old, mature trees, which are more prone to injury and wounding.
The female lays almost 90 white-coloured eggs, which turn pink as they mature. It takes them 2 to 3 weeks to hatch into the larva, which feeds on the tree bark.
The larva keeps tunnelling into the bark as it grows and pupates in it throughout the winter season to emerge as an adult in the spring.
One key factor in identifying a cherry bark tortix infestation is to look for reddish frass near the bark.
There is usually only one generation a year.
