Forest insects are a diverse group of organisms that play crucial roles in forest ecosystems. They include species such as beetles, ants, and caterpillars, which contribute to processes like decomposition, pollination, and nutrient cycling. Many forest insects are herbivores, feeding on leaves, bark, and wood, while others are predators or parasites that help control pest populations. These insects also serve as a food source for various animals, including birds and small mammals. Some forest insects, like butterflies and moths, are important for pollinating plants, while others, such as termites, aid in breaking down dead wood. Understanding forest insects is essential for maintaining healthy forest ecosystems.
