6787. We have been finding these beetles “dead” on our second floor for a few weeks. The last few days we have found moving ones during the day as well. We recently completed a renovation on our home and want to make sure these pests are doing any damage. East York, Ontario. Canada

Number 6787. This appears to be an elm-leaf beetle, Xanthogaleruca luteola (Coleoptera: Chrysomelidae). They sometimes will enter buildings for winter shelter, but will do no harm there. Click here for more detailed information.
