Although dragonflies are predators, they themselves must worry about predators, also. Birds, frogs, lizards, spiders and fish think dragonflies are pretty tasty. So the things you do to attract them must also protect them. 2. Blooming plants attract bees, butterflies, and other pollinators that dragonflies like to eat.
After puncturing the skin with their mouthparts and feeding on blood, mosquitoes leave hard, itchy bumps. In the blood-feeding process, mosquitoes inject saliva into their host which creates the reactions that cause bite symptoms. Most mosquito bites are harmless and the symptoms subside in a few days. Some discomforting symptoms include swelling of the bite site, soreness, and bleeding. While mosquitoes are an itchy, uncomfortable nuisance, the important problem arising from mosquito bites is transmission of viral or parasitic diseases.
First, a mosquito bite can cause irritation of the skin because of an interaction between our bodies and the mosquito body fluids. This causes a red (sometimes swollen) bump that can be very itchy. These bites have very variable healing times. For some people, a minor bite can heal in one day. For others, the bump can last for more than a week. Your bite that has been there for two weeks is right at the time point where I would begin to worry that there may be an infection in the area.
