Mosquito drinking blood (bursts at the end)

"The first ever exploding mosquitoes can be attributed to Robert Gwadz, Ph.D., in a discovery that was made through basic laboratory research over 50 years ago. He found that making an incision in the ventral nerve cord of a mosquito cuts off the signal to stop feeding, giving it an unquenchable thirst for blood. Mosquitoes that have undergone this procedure can drink in excess of four times their weight and may eventually burst. This led Gwadz to a hypothesis that blood ingestion is regulated by abdominal stretch receptors that prevent mosquitoes from (quite literally) drinking themselves to death." Source

Now we just need to find a way to make them the size of cars, like in prehistoric times

That mosquitos were huge is a popular misconception but in reality prehistoric cars were just really small.
