Understanding Sawflies: Identification, Life Cycle, and Control Measures

Sawflies are a type of insect that belongs to the order Hymenoptera, which also includes bees, wasps, and ants. They are so named because their larvae have a distinctive saw-like mouthpart called a mandible that they use to feed on plants.

There are over 100 species of sawflies found in North America, and they can be recognized by their slender bodies and narrow waists. Adult sawflies have two pairs of wings, with the hind wings being larger than the front wings. They typically have a metallic sheen to their bodies and may be colored in shades of green, blue, or black.

Sawfly larvae are often mistaken for caterpillars, but they have a few key differences. Sawfly larvae have a distinctive head capsule and a pair of mandibles that they use to feed on leaves and other plant material. They can be found on a variety of plants, including trees, shrubs, and herbaceous perennials.

Sawflies are generally not harmful to humans or pets, and they do not sting or bite. However, their larvae can cause significant damage to plants if they are present in large numbers. If you suspect that sawflies may be present on your plants, it is important to monitor them closely and take action if necessary to prevent further damage.
