How to spot sawfly damage

Identifying Sawfly Damage: A Simple Guide

Sawflies are a type of insect that can cause significant damage to plants and trees. They are often mistaken for wasps due to their similar appearance, but they do not sting. If you suspect that sawflies are damaging your plants, it is important to act quickly to prevent further damage. In this article, we will go through a step-by-step guide on how to spot sawfly damage.

Step 1: Look for chewed leaves

One of the most obvious signs of sawfly damage is chewed leaves. Sawflies have strong jaws that they use to chew through leaves, often leaving behind irregularly shaped holes or notches. If you notice that your plant's leaves have been chewed, inspect them closely to see if you can spot any sawflies.

Step 2: Check for larvae

Sawflies lay their eggs on the leaves of plants, and the larvae that hatch from these eggs are the ones that cause the most damage. Look for small, green or yellow caterpillar-like creatures on the leaves of your plants. They may be difficult to spot at first, but if you look closely, you should be able to see them.

Step 3: Look for sawfly adults

Sawflies are active during the day, so if you are having trouble spotting the larvae, you may be able to spot the adults instead. Sawflies are about 1/4 to 1/2 inch long and have a wasp-like appearance. They have two pairs of wings and are usually black or brown with yellow or white markings.

Step 4: Check for webbing

In some cases, sawfly larvae may spin webs around the leaves of plants. This can make it difficult to spot the larvae themselves, but if you notice any webbing on your plants, it is a good indication that sawflies are present.

Step 5: Look for plant damage

Sawflies can cause a range of damage to plants, including defoliation, stunted growth, and even death. If you notice that your plants are not growing as well as they should be or are showing signs of stress, it could be due to sawfly damage.

In conclusion, spotting sawfly damage requires a keen eye and close inspection of your plants. Look for chewed leaves, larvae, adults, webbing, and plant damage to determine if sawflies are present. If you do spot sawfly damage, it is important to act quickly to prevent further damage to your plants.
