Yes ! Of course there is ! You need a male moth & a female moth to reproduce the species !
A female silk moth cannot and will not mate with a female silk moth. She will mate with a male silk moth if one is available. If not, she will simply die.
A Male moth has a more broader body than a male
Adult Polyphemus moth's life span is only about a week. The male and female mate and the female lays her eggs during this time span.
Female moths emerge from their cocoons with all their eggs fully formed in their abdomens, and the eggs are not fertilized until they are being laid (by male gametes stored in the female's spermatheca from mating). They keep laying eggs until they die in most cases. In other words, almost any female moth you find is a "pregnant moth", which is why there is no literature on behavior of pregnant moths.
the female moth sends something like a perfume that attracts the male moth
female moth lays the eggs on the mulberry leaves
The female Eurasian Eagle Owl, the average wingspan of male and female is around 5.2 ft. In birds of prey such as Owls, Falcons, Hawks, Kites, Harriers, Eagles, etc... the Female is about 1/3 larger than the male.
Male emperor moths are equipped with large, feathery antennae which have great quantities of olfactory receptors on them. The antennae are spread out to come in contact with as many scent molecules as possible allowing them to detect females from great distances.
The ovaries do not actually produce a female gamete each moth. The ovaries prepare a female gamete for fertilization every month.
The female yucca moth chooses to go to nearby yucca plant in order to get the pollen from the plant. The moth then starts to lay eggs in the large flowers of the yucca plant.
Pheromones....
The female moth releases a pheromone when she is ready to mate that can be detected by male moths up to a mile away. The female moth will only mate with the male that reaches her first.
