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.
After limited exposure, you get a delayed reaction of intense itching and redness several hours after a bite. 3. Increased exposure to mosquito bites provides an immediate reaction in one or two minutes that only lasts an hour. 4. With more continual exposure, the delayed reaction vanishes.
