American mosquitos stay up late

Many recent changes in organisms have been chalked up to climate change. A North American mosquito species has evolved to wait longer before going dormant for the winter. Mosquitoes with genes that cause them to go dormant later were probably favored because it allows the insects to gather more resources during our new, extra-long summers.
