1. Appearance: Mealworms are about 2.5 cm (1 inch) long when fully grown and have a segmented, yellowish-brown body with a hard outer shell.
2. Diet: They feed primarily on grains, cereals, and decaying plant matter, making them common in grain storage areas and pantries. They are sometimes considered pests because of their tendency to infest stored food products.
3. Life Cycle: Mealworms undergo metamorphosis, transitioning from larvae to pupae and then into adult beetles. The larval stage can last several months, depending on environmental conditions.
4. Habitat: Mealworms thrive in dark, moist environments where food sources like grain, bran, or decaying plant material are available.
