When the Asian tiger mosquito (Aedes albopictus) arrived in the United States in the 1980s, it took the invasive blood-sucker only one year to spread from Houston to St. Louis. New research from Washington University in St. Louis shows that the mosquitoes at the northern limit of their current range are successfully using time-capsule-like eggs to survive conditions that are colder than those in its native territory.
