Daniel Sherwood poked the long-handled dipper into the manhole. "Let's see if we can get any here." He peered into the stagnant water in the dipper. "Look at this; we have all four instars in here. These rafts are filled with eggs, and each raft can have 50-100 mosquitoes. See that little guy wiggling around in there," he said. "He is getting ready to pupate. We are really concerned about the pupa. When they get to the fourth instar stage, they stop eating and start laying eggs."
