Where does the Alfalfa Weevil lay its eggs?

The Alfalfa Weevil lays its eggs in dead hollow alfalfa stems. This behavior is a strategic choice, as it provides a protected environment for the eggs, helping to ensure their survival against environmental factors and predation. The hollow stems offer a safe space, shielding the developing larvae from potential threats and providing access to food sources once they hatch.

In contrast, laying eggs on the leaves of plants or in the soil does not offer the same level of protection or immediate access to a food source, which is crucial for the larvae's survival upon emerging. Additionally, utilizing the hollow stems takes advantage of the plant's structure to enhance reproductive success.
