habitat
Weakened pine and spruce species with a DBH of 50 cm or more; may also attack healthy trees.

seasonality
Flight period is from May to October. In warmer climates adults may fly all year.

identification
This species has a reddish brown color, small punctures on the lateral parts of the pronotum, as well as small granules on the declivity. It can be distinguished from D. terebrans by its distribution as well as these characters.

life history
This species will overwinter as partly grown larvae, or as young or mature adults. The adults will find the host tress some time after the primary attacker has attacked and weakened the tree. Egg galleries are variable. No egg niches are excavated, eggs are separated by frass. Oviposition begins in late May or June. Larvae will hatch within 10 days and then mine the phloem region in groups. The larvae will mine the phloem for at least two months. The larvae will mature and create pupal cells out of frass. Generation times vary by species. In the north a generation can take a year or longer, at southern latitudes 1.5 generations can be completed in a year.

conservation
This species is considered a pest throughout its range.
