Lawn grubs can be a frustrating problem for homeowners in Australia as they can cause damage to the lawn by feeding on the grassroots. In order to effectively control these pests, it is important to understand the different types of lawn grubs and their life cycles. In this blog post, we will explore the types of lawn grubs commonly found in Australia and their life cycles.
The African black beetle is a common lawn grub in Australia. The larvae are white, C-shaped, and have a brown head. They feed on the roots of grass and other plants, causing the lawn to turn brown and die. African black beetle larvae typically hatch in late summer or early autumn and feed until the winter. In the spring, they move deeper into the soil to pupate and emerge as adult beetles in the summer.
The Argentinian scarab is another common lawn grub in Australia. They have a white, C-shaped body with a brown head and six legs near the head. These grubs feed on the roots of grass, which can cause damage to the lawn. They typically hatch in late summer and feed until the fall, when they move deeper into the soil to overwinter. In the spring, they return to the surface to pupate and emerge as adult beetles in the summer.
Billbugs are a type of lawn grub that is becoming more common in Australia. They have a long snout, which they use to bore into the stems of grass and other plants. The larvae are white, C-shaped, and have a brown head. Billbug larvae typically hatch in the spring and feed until the fall. In the winter, they move deeper into the soil to overwinter. In the spring, they return to the surface to pupate and emerge as adult beetles in the summer.
Cutworms are a type of lawn grub that feeds on the foliage of grass and other plants. The larvae are typically grey or brown and can be up to 50mm long. They often curl up into a C-shape when disturbed. Cutworms typically hatch in the spring and feed until the fall. They then move deeper into the soil to overwinter. In the spring, they return to the surface to pupate and emerge as adult moths.
Sod webworms are another type of lawn grub in Australia. They are the larvae of a moth and are typically green, brown, or grey in colour. Sod webworm larvae feed on the blades of grass, which can cause brown patches on the lawn. They typically hatch in the summer and feed until the fall. In the winter, they move deeper into the soil to overwinter. In the spring, they return to the surface to pupate and emerge as adult moths.
The life cycle of lawn grubs in Australia: The adult beetles lay their eggs in the soil during the summer months. The larvae hatch and feed on the roots of grass and other plants. They then move deeper into the soil to pupate in the fall or winter. In the spring, they emerge as adult beetles and the cycle begins again.
