How many pairs of blue spots do spongy moths have?

The correct answer is that spongy moths have five pairs of blue spots. Each of these pairs is located along the wings of the moth, contributing to their distinctive appearance. This feature is significant for identification and can help distinguish spongy moths from other species, especially during pest management and ecological studies.

Understanding the anatomy of spongy moths, including their wing characteristics such as the identifiable blue spots, is crucial in recognizing and controlling their populations, as they can be invasive. This five-pair configuration is a key factor for entomologists and ecologists engaged in research and fieldwork.
