What's That Bug? does not endorse extermination

hi bugman.. I came home to find the wall outside my backdoor in Southern Cal. covered with these beasties. They all seemed to be climbing up to my roof and appeared more rarely around other outside walls.
Do I need to call the exterminator? Or should I make peace with them? My dog hasn’t noticed them yet.

Hi Andy,
This is a Mourning Cloak Caterpillar which will become a lovely brown butterfly with cream colored wing edges and blue spots. The caterpillars feed on elm, willow, poplar and occasionally the floss silk tree.
