Anonymous users2024-02-15Dragonfly eyes are compound eyes, i.e. large eyes are made up of many small single eyes.
The advantage of the eye is that it can mention a wide field of vision for animals, and can effectively calculate the orientation and distance between itself and the object being observed, so as to facilitate the rapid judgment and response of compound eye insects; In some examples, the compound eyes of insects are even able to resolve the polarization of light. The spatial resolution of compound eyes is often inferior to that of human eyes, but the temporal resolution is also much superior, up to 10 times.

Anonymous users2024-02-14Dragonflies have short, bristly hairy antennae with many receptors distributed on them. The main types of receptors are cone-receptors, cavity-cone receptors, plate-shaped receptors and jar receptors. Studies have shown that different species of dragonflies have different types of receptors, and their numbers and distribution forms are also different.
The receptors of female dragonflies are stable in the same family, the same genus and the same species, while there are obvious differences between different families and genera, although the differences between different species in the same genus are small, but the differences between individual species are still very obvious, so the receptors of female dragonflies also have certain significance in the classification.
