do all flies start out as maggots?

Question

ok my brother and husband and i are having this little dispute,
they are saying that not all flies start out as a maggot and i say yes they do, what are some of your oppinions to help us decide on who is right or wrong, thanks

Answer 1

Opinion? How bout facts. Flies, Dipterans are insects. They have what we biologist call complete metamorphic life cycle. Flies start life as an egg.

The house fly has a complete metamorphosis with distinct egg, larva or maggot, pupal and adult stages

Answer 2

Flies And Maggots

Answer 3

In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. One jar was left open; the other was covered with a cloth. Days later, the open jar contained maggots, whereas the covered jar contained no maggots. He did note that maggots were found on the exterior surface of the cloth that covered the jar. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation. Or so he thought.

Answer 4

No, they start out as an egg. What follows is my five cent explanation plus a very condensed explanation of metamorphosis.

All insects hatch from eggs. The egg is, therefore, the first life stage of all insects.

Flies are insects, therefore, they come from eggs. Flies go through what is referred to as "complete" metamorphosis; in other words, they go from egg to larva (maggot) to pupa to adult. Counting the egg stage, there are four stages in "complete" metamorphosis. The larval stage of a fly is a maggot. The larval stage of a butterfly is a caterpillar. If the immature (larval) stage of an insect spends part or all of its life in water, it is sometimes referred to as a naaid.

Metamorphosis herein refers to a change in "form" following (after) the egg stage. A change in "form" does not herein refer to size or maturation, it is limited to a change in "form."

Some entomologists now classify metamorphosis into three categoies: 1) simple (includes those without change in form), 2) gradual or incomplete, and 3) complete.

Some insects, silverfish for one example, do not, after hatching from an egg, change in form: immature silverfish look like mom and dad, except they are smaller. Therefore, you could say that silverfish are without metamorphosis; no change in form.

Some insects,roaches for one example, undergo gradual or incomplete metamorphosis; egg, nymph, adult. Counting the egg stage, there are three stages. Imature roaches look similar to mom and dad, but have no wings until the adult stage.

I hope this is helpful, and please pardon any typos.

-WARNING- The maggots will encroach on your spider's web taking over and spreading disease and misery to his spider family. The maggots will then force him to Walk a trail of tears to WebOregon where they will set up a foe reservation where the spiders will be under fed and under clothed. This will lead to generations of alcoholism in the spiders blood line because of their deep sorrow for their spider ancestors. They will then start their own governments that will not be supported or controlled by the maggot overlords. Which then the lowly spiders will rise up once more and take back their web.

Answer 6

No, they start out as eggs and because they have complete metamorphosis go through the larval (maggot), and pupa, to the adult stage.
