Unfortunately, chances are by now your pumpkin is looking more like this:

If you're lucky you can get it to the trash or compost without the bottom falling out (I wasn't that lucky). Even if you didn't carve a scary face in it, it will likely be in decline seeing as it is a fruit off the vine and it is slowly being broken down by bacteria and fungi. If there is a wound on the pumpkin from rough transport, it opens the pumpkin to these microorganisms. This is prime food for many insects that love to eat the nutritious soup.
Most of these insects are flies. Flies love rotting vegetable matter. Vinegar or fruit flies (Drosophilidae) are particularly fond of rotting fruit. Some walk all over their giant bounty, waving their patterned wings around while seeming to dance. They do this to attract mates and establish that they have found a nice source of food for their precious little maggots.

Other common flies include dark winged fungus gnats (Sciaridae) whose larvae love to eat the molds and other fungus growing happily on the pumpkin flesh. The small black flies swarm around the pumpkin and settle after a disturbance.

Many other fly species may be found among the decaying Jack-O-Lantern as well. However, flies aren't the only visitors to such a great source of food. Beetles, earwigs, isopods (sowbugs & rolly-pollys), slugs/snails, and other organisms like this type of substrate to feed on as well.

Of course, if you are responsible and discard your pumpkin while it is still fairly fresh, you won't have to deal with these insect and other small animals. But then again you may not see some of these cute little critters setting up shop and recycling your autumnal fruit festivity. Oh well, they can find the compost bin too I guess...
