We found this insect in our house on the coast in San Diego California during the month of September. Based on the pictures on your site, it looks like the red shouldered pine borer or a blister beetle? We cannot tell. Please help!

This is a Red Shouldered Bug, Jadera haematoloma, a species that frequently forms large aggregations around homes and gardens. Though it can be a nuisance when it appears in large numbers, it is considered a benign species.
