Each native plant species has a suite of insects that depend on it for food. In addition to the conspicuous ones that visit flowers or eat leaves in plain sight, there are many that are hidden from view. Many herbivorous insects are so specific in their habits that they can be identified to species by examining the evidence they leave on their host plants, without ever seeing the animals themselves. Signs of highly host-specific insects are sometimes so distinctive that they can also help us identify the plants they are found on. On this walk at BNRC’s Thomas & Palmer Brook reserve, we will explore many of these fascinating plant-insect interactions. Be prepared to move slowly and study very small things—the less ground we cover, the more we will see!
