Males are smaller than females.
Walking Sticks lay eggs, and once they start they lay many. At best, you will see their abdomen looks bigger.
For most walking stick insects, the entire species is female and reproduction only requires one bug (parthenogenesis). Some species, though, do mate male-female.
If you have both as pets you will notice on the tails of the Stick Insects that the female will be larger than the male both in height and length and she will be laying eggs if she is fully grown, also the females usually have small antenna. For the males it's the oppisite.
Females do not need the males to reproduce but... the nymphs will only be females if the female does not reproduce with a male. (I'm trying not to be rude...)
Do you mean female and male? If so, then the female betta fish is smaller and less elaborate than the male.
A male stick insect will not lay eggs. However, a female stick insect is parthenogenetically, and can lay eggs without mating with a male.
This depends on the species. For most, there are male and female stick insects, but there are species (like the Indian Stick Insect) that are populated by all females. The female is larger than the male.
youre axolotile is a male it will have lumps on the side of it at the back
No they can be introduced while in heat.
This depends on the colouring of the species, but no, not all male stick insects are black. Most of the time both genders have the same or similar colouration.Both male and female Peruphasma Schultei stick insects are black.
The majority of walking stick-type insects do not migrate. The majority, instead, hibernate during colder seasons. They also have a short lifespan,
The male inserts his penis into the female's vagina.
