thrips
Western flower thrips (Frankliniella occidentalis).
In regions with cold winters, thrips survive the season by hibernating as either adults or immature forms. They typically seek shelter in detritus, hollow stems, or within the ground.1
For those populations that do not survive the cold, the local presence of the insect is restored each year by spring migrants arriving from warmer regions.1
