Science Sunday: Fruit Flies part 2

We have been observing fruit flies for a little over a week.  No I never did get rid of them completely so it was easy to catch enough to observe.  We actually caught them in two jars, but I focused on the one. It was actually weird.  The jar we observed more closely had 1/2 of a not very good peach (they had all been dry and tasteless thus I figured I would get more use out of them by feeding them to fruit flies).  The other jar had the other half of the same peach plus some strawberry tops and, I think, a blueberry.  The fruit flies in that jar seemed to be more numerous at first, but it didn't have near the same amount of maggots (if that is the correct term for the larva stage of fruit flies) as the other jar.  The peach in our observation jar ended up disintegrating to mush, but the other one still has shape to this day.  Though there was more juice in it at first and I wonder if the larvae drowned?  No clue.  Anyhow, the girls, Tabitha specifically, got as excited as I did when I would call them over to see something new I had observed.
Day 1: I set out the jars with the peaches over night and in the morning I very very quickly covered the jar with a cut up piece of pantyhose held on with a rubber band.  I wish I could have had an accurate count, but they are constantly in motion.  I was estimating 20.
Day 2: There was no visible change
Day 3: We observed several maggots slithering around on the fruit and the bottom of the jar.
Day 4: Many, many maggots were all over the inside of the jar, I made sure none were sneaking out from underneath the rubber band.  Won't make that mistake again.  I found it interesting watching them move.  I guess I would say they move like worms.  The front juts out and the rest of the body catches up with it.  What was really interesting was noting that the midsection of the maggot is slightly darker and I could watch it undulate as it moved.
Day 5: Some of the maggots are entering the pupa stage, they are a cream color.

Day 6: Most of the maggots are now in the pupa stage.
Day 7: The pupa are getting darker, close to brown.
Day 8: At 2:00 pm I saw 1 new fruit fly.  It was very light in color compared to the mature fruit flies caught last week.
Day 9: The jar is full of fruit flies.  They tend to gravitate to the opening and if you hold it up to your ear you can hear the buzzing.  No, I am not counting them!!

We made a Fruit Fly Life Cycle Book:
