Why female weevils have long proboscis?

Answer 1

Female weevils have long proboscises as they use it to lay their eggs. The proboscis is a specialized organ that allows them to drill into plant material to reach the reproductive tissues where they can lay their eggs. The length of the proboscis and the shape of the tip help the female weevils to target the right parts of the host plant and lay their eggs precisely, ensuring the survival of their offspring. Additionally, the proboscis is also used to feed on plant sap for nourishment.
