This is our version of Groundhog Day: Imported cabbageworm butterfly day! 

Found this guy in our living room, this morning, looking for a place to warm up.

According to Wild Maryland 101 blog spot:

“They are very common and cold tolerant, and are often the first butterflies to be seen in early spring.  For this reason, many Marylanders consider this non-native butterfly a harbinger of spring.” 

Pieris rapae, also known as small white butterflies, European cabbage white butterflies,  small cabbage white butterflies, and piéride du chou like we say in French.
