Black-and-red Bug (Small Milkweed Bug)
The Small Milkweed Bug (Lygaeus kalmii) is a colorful insect commonly found on milkweed plants. It is easily recognized by its black and red pattern and is often seen feeding on milkweed seeds.
Identification
Adult small milkweed bugs measure about 1/2 inch long. Their bodies are bright orange-red with black markings forming a distinctive X-shaped pattern across the wings.
Distribution and Habitat
This species occurs widely throughout North America wherever milkweed plants grow. It is commonly found in gardens, meadows, and roadside vegetation.
Life Cycle and Behavior
The life cycle includes egg, nymph, and adult stages. Nymphs resemble smaller versions of adults but lack wings. Both stages feed primarily on milkweed seeds.
Pest Status
Small milkweed bugs are not typically considered pests because they feed mainly on wild plants rather than cultivated crops.
Prevention
No prevention is needed since these insects rarely cause significant damage.
Control
Control is generally unnecessary. They are part of the natural ecosystem surrounding milkweed plants.
