What are the characteristics of dragonflies when it rains?

Dragonflies flying in groups at low altitude indicate rainy weather. This is because the air humidity is high at this time, and the wings of small insects are very wet, so they can't fly high. Dragonflies feed on small insects. This time is a great opportunity for dragonflies to hunt.

According to these characteristics of dragonflies, people have summed up some laws: before and after the hot summer, red dragonflies fly in low altitude in groups in the field, which indicates that it will be dry and hot weather soon. Before and after beginning of autumn, yellow dragonflies hover low in the fields, which means that there will be continuous rainy weather soon.

Life habits of dragonflies

Dragonflies like wet environment, so they usually fly in ponds or rivers, and their larvae (larvae) also need to develop in water. Odonata is a semi-metamorphosed insect, which has only three stages in its life: egg, larva and adult. Adults often lay eggs in water by skimming. Larvae, also known as hydra, preys on other aquatic organisms in the water, climbs out of the water before emergence, mates and lays eggs, and completes its life history.

Dragonflies not only prey on other insects, but also have the habit of adults eating each other among species. When they prey, they will catch their prey fiercely, and there are a lot of coarse hairs on their feet, which can help them catch their prey and make it impossible to escape. The mouth is also quite developed, it can bite prey, facilitate eating, and can eat up food equivalent to its own weight within 30 minutes.
