Why would God make Mosquitoes?

Good summer question I thought. Here is a good answer from Answers in Genesis:

"...animals thought to be strictly carnivorous can and actually do survive on a vegetarian diet... These groups, conventional thought says, are carnivorous. The mosquitoes comprise the first group of interest. It appears that only the females of certain mosquito species actually consume blood. The reason blood is needed is because ‘females, at emergence, have only partly developed ovaries. This requires a source of nitrogen to complete ovarian development and reach maturity.’ Mosquitoes that do not draw blood find nutrition by feeding on plant nectar. So it seems that only a portion of mosquitoes use blood, and it is only mammalian blood. This amount would not include males since they do not consume blood. Nor would it include those few species where the females use nectar. So the percentage needing blood is under 50% of the total mosquito population. This could suggest that at some point in history a change took place that caused only some female mosquitoes to use blood as food.”

What was the change? If we look into the Bible we see the answer: Man's sin. Before the fall only plants were given for food. (Gen. 1:29-30) With the curse, came death, and death and suffering for the whole world. (Rom. 8:22) So next time you get mad at the mosquitoes, remember that this is to remind us to get mad at our own sin, and then to remind us that it will not always be there. Our Savior, Jesus Christ, will ransom us from all suffering one day, even mosquito suffering!
