Reproduction?

Question

how do butterfly reproduce? and i need details, ugh this project got me wasting all my points;'(

Answer 1

The only goal in life for an adult butterfly is to reproduce. The males look for females to inseminate. The females lay eggs.

Within the males' abdomen are the sperm producing organs. When the male mates, a set of "claspers" at the end of the abdomen will open and clamp down on the female's abdomen. Butterflies mate facing in opposite directions with their abdomens attached.

The penis enters the female at the same location where the eggs come out. When the male ejaculates, the semen enters a small storage pouch inside the females abdomen. After mating, the female has about 100 eggs inside her and a pouch full of the male spermatozoa. Once gravid, she will perform a kind of self-fertilization. When she places an egg on the hostplant, as the egg is passing out of her ovipositor, it will pass this pouch. At that instant, one spermatozoa will fertilize the egg and determine its sex. When the egg is first placed on the leaf, it was fertilized less than a second before.

A typical female butterfly will lay about 100 eggs in her lifetime. Some species lay their eggs gregariously (in clusters). Other species lay their eggs individually on widely dispersed plants. One school of thought argues for "survival in numbers" while the other takes the perspective, "don't put all of your eggs in one basket". Both approaches are valid, but only just sufficiently to ensure the survival of the species.

Of the 100 or so eggs that may be laid, only 2% should be expected to survive to become healthy adult butterflies. This figure is reasonable since in the aggregate one egg will replace the female and the other the male. The other 98% will fall by the wayside in the course of their development as eggs, larvae, pupae and emerging adults.

The reasons for this high mortality rate are several. The most important causes include climatic conditions (wind, drought and rain); diseases caused by virus and bacteria; and predators.

Answer 2

Butterfly is a holometabolic insect. You have to have male and female butterflies for that. They have to be given food and shelter as natural as possible.Male and female will mate. The female will lay eggs on leaves or whatever. Within a few days the eggs will be hatched.The caterpillar will come out of the egg. This caterpillar will eat a lot of leaves.It will be active. You have to watch its movement and provide food. In a week or so it will get very sluggish and will be transferred into pupa. A pupa is a barrel shaped structure. In a span of two weeks or so, from this pupa, an adult butterfly will emerge. It will stretch its wings and try to fly with success.
You have to note when the eggs were laid, what was their colour.
After how many days the caterpillar hatched from egg.
What was the length and colour of the caterpillar.
For how many days did the caterpillar eat.
For how many days did the pupal stage last.
When did adult butterfly emerge from the egg and what was its wing colour and pattern.
