Most mosquitoes are harmful and annoying. But did you know there are types of mosquitoes that are not harmful and are actually useful to us humans? For example the elephant mosquito, they only feast on sugary liquids such as flower nectar and the juice from rotting fruit. The most shocking part is that they can also feast on other dangerous mosquito larvae which helps control and reduce the number of harmful mosquitoes! Their trick is they extend their head from their body only leaving a tiny connection before they devour its prey. The only catch is, they have to be in the same body of water.
