When does the Fletcher Scale begin its life cycle?

The Fletcher Scale, which is a scale insect that affects a variety of plants, begins its life cycle in late May. During this time, the weather conditions are typically conducive for the development of scale insects, as temperatures rise and humidity levels increase following spring. This period allows the eggs laid by adult females to hatch, leading to the emergence of the first instar nymphs, commonly known as "crawlers." These crawlers are the mobile stage of the insect that will establish themselves on host plants.

In late May, the life cycle is characterized by the initiation of the feeding phase, which occurs after the crawlers settle on the plant. Understanding the timing of their life cycle is crucial for effective pest management, as this is the optimal time for implementing control measures to prevent population explosions throughout the growing season. Recognizing late May as the beginning helps applicators plan their monitoring and treatment strategies efficiently.
