- This insect is an extremely common fig pest.
- Adult: it emerges on sunny days and occurs all year round, even in the middle of winter, on the branches of fig. Individuals of both sexes establish the colony in branches of small diameter on withering trees: the gallery begins with a mating chamber leading off to 2 transversal egg-laying corridors, one to the left, the other to the right. The eggs are deposited as drilling of these corridors progresses.
- Larva: larval galleries are perpendicular to the egg-laying corridor, straight, parallel to each other and short (*) . The gallery contains 30 to 40 larvae on average.
- At least 3 or 4 annual generations.
Adults and larvae occur throughout the year but larval development during the winter period is protracted.
This pest attacks weakened fig trees; it accelerates their withering and prevents any recovery of sickly subjects.
