Red-headed pine sawfly

Red-headed pine sawfly

Neodiprion lecontei

A species of Neodiprion

A distinctive creature, red-headed pine sawfly showcases striking adaptations to its environment. Its larvae are voracious, predominantly feeding on the needles of coniferous trees, with a preference for pines, which serve as a crucial resource during their development. The adult form is less destructive, sustaining on nectar and playing a role in pollination. Their survival strategy sees them through winters in the egg stage, ensuring an early start at the onset of warmer weather.

Egg The freshly laid eggs of red-headed pine sawfly are often oblong or elliptical, with a protective casing. They are typically attached to leaves or stems, and the color may blend with the plant material.
Larva After hatching, the larvae of red-headed pine sawfly appear worm-like with a segmented body. They primarily focus on feeding and growth, molting several times and increasing in size with each stage.
Pupal Red-headed pine sawfly's pupal phase occurs in a cocoon or beneath soil. The pupae are inactive as they undergo a dramatic transformation, restructuring their body into the adult form.
Adult Emerging from the pupa, the adult red-headed pine sawfly develops wings and functional reproductive organs. The body is fully formed and hardened, and the adult focuses on reproduction and may exhibit sexual dimorphism.

Egg Eggs of red-headed pine sawfly are often laid in clusters on the undersides of leaves of the host plant. Inspect the leaves by looking for small, oval-shaped eggs that are typically in a row or a grid pattern.
Larva Larval red-headed pine sawfly are found on their host plants. Search for chewed foliage or frass (insect waste) around plants and look for the caterpillar-like larvae.
Pupal Pupae of red-headed pine sawfly may be found in the soil or in a sheltered location near their host plants. Look for cocoons or pupal cases hidden under leaves or in crevices.
Adult Red-headed pine sawfly adults are winged and capable of flight, making them slightly more challenging to find. Look near flowering plants, especially where there is an abundance of nectar, as adults will be seeking food.

Agricultural Pests

Larvae of red-headed pine sawfly consume the foliage of several plants, resulting in defoliation that can range from mild to severe. A small number can cause noticeable leaf damage, while large infestations may lead to significant crop loss. This defoliation can impact photosynthesis, weakening the plants and potentially affecting yield and quality, leading to economic losses.
