During a year, five trees of this species were monitored. Adult flies were collected and measurements of diameter and depth of the holes as well as height of attack of larvae on the trunk were made. Seven adults were observed. The average diameter and depth of galleries in the transversal direction were 0.8 cm and 19.1 cm, respectively. The height of attack varied from 1 m to 3 m from the ground level.
