Life history

Adults feed preferentially on members of the pine and spruce families for up to seven days after emerging between mid-June and mid-August. After mating, females chew small egg niches into dead or dying trees or logs, into which they deposit one egg each. Both sexes mate repeatedly with different partners, and females have been found to lay between 15 and 20 eggs on average per lifetime. Once the larvae hatch, they burrow into the phloem and to the cambium, where they c…

In boreal forests where fire has altered the landscape, changes come to plant communities and carbon flux. This change opens up opportunities for immigrant species to move into a competitor-free habitat. Several groups of insects, including the genus Monochamus, have become adapted to exploit these conditions. M. scutellatus is a saproxylic insect, which means that at least part of its life cycle is dependent on either dead or dying wood. For these beetles to successfully coloni…
