How do you tell a boy from a girl silkworm?

To differentiate between male and female silkworms, you can examine their physical characteristics. Male silkworms are typically smaller and have more pronounced, bushy antennae, which help them detect pheromones. In contrast, females are larger, with thinner antennae and a rounder abdomen, especially when they are ready to lay eggs. Observing these traits can help you identify their gender accurately.
