What is a primary characteristic of midges that distinguishes them from other biting insects?

Midges are unique among biting insects due to their inability to bite humans and larger animals. This characteristic sets them apart as many other biting insects, such as mosquitoes and biting flies, rely on blood meals for reproduction and energy. Instead, midges feed on plant nectar as adults. This feeding behavior, along with their small size and limited wing structure, contributes to their distinct classification.

While midges may lay eggs in significant quantities, especially in favorable environmental conditions, this does not specifically define them as a primary characteristic in comparison to other biting insects. Similarly, midges are smaller rather than larger than many other biting insects, and unlike bees and other insects which are recognized for their wings, midges possess wings but are not equipped to bite. This distinction is crucial for understanding their role in ecosystems and their interactions with other species.
