Will our cold weather snap eliminate mosquitoes?

Christmas weekend was cold, no doubt.  But was it cold enough to kill off mosquitoes? We shook and shivered like no other through the recent holiday weekend.  Are mosquitoes hearty enough to have survived?  Here in Central Mass, the low temperature reached single digits on Christmas Eve and Christmas day.  Some of us had to take safety measures for our outdoor animals during this cold snap.  How on Earth could small animals and insects survive it?
