We found both of these (same butterfly) in the house, it’s white yellow with a few spots. Can you tell me what it is?

Dear Marie-Eve,
These pretty little butterflies are Cabbage Whites, a European species thought to have been introduced into North America in the 19th Century.  According to BugGuide:  “Introduced accidentally near Montreal in the 1860s, this species has become an important pest. Bacterial and viral diseases now provide some biological control.”  Caterpillars feed on cabbage and many other plants in the same family.
