I think Jackson33 is probably correct, some of the insects may indeed have been carried by the storm and left behind as it travels but the bulk are hatched out soon after. a hurricane isn't a two hour event like a thunder storm, one time we were in hurricane conditions for almost 24 hours and the storm it's self affected the weather for days before the storm with heavy rains. By the time the storm was over a huge amount of really mean mosquito's had been hatched out from islands nearby that were normally dry. I've seen birds sheltering in low bushes and even under large objects during the storm. Some birds may even be able to fly above the worst of the storm. The wildest thing is how reptiles and other small animals head for high ground. during one hurricane a family that lived hear me heard an intense noise at their door like someone was trying to break in, they opened the door and found an six foot alligator on their porch trying to get in the door! Rattlesnakes and just regular snakes, lizards, and small mammals often turn up in yards due to humans building on high ground. Animals seem to be able to survive the storms better than a human out in the open for sure!
