How many cockroaches hatch from one egg? What are the differences in the masonry of individual species of parasites?

How many hatching cockroaches from one egg? The presented question has generated the whole mass of errors and unreasonable conjectures. Some eyewitnesses claim that saw whole hordes of insect parasites that come out of one cocoon. Let's find out how many cockroaches hatch from one egg in fact.

What is an egg of a cockroach?

How many cockroaches hatch from one egg? This issue will be discussed later in our material. In the meantime, let's find out what exactly are the eggs of such insects.

Larvae of cockroaches hatch from the so-called ootheca. The latter is an egg storage in the form of a cocoon, which is covered with a rather malleable chitinous membrane. An ootheque in the body of the female cockroach develops. Under favorable conditions, several dozen eggs can form in this cocoon.

After the ripening of the insect embryos, the ootheque separates from the body of the female. The egg shell quickly hardens and converts into a reliable protective capsule. Such a container for larvae protects the offspring of cockroaches from the impact of a number of unfavorable environmental factors.

Differences between the laying of individual species of cockroaches

Before we find out how many cockroaches hatched from one egg, let us consider what morphological differences are there in the ootheki of certain types of domestic pests:

1. Black cockroaches lay cocoons, the length of which is about 12 mm, and the width - up to 6 mm. Such ootecs have a uniform dark color. On their surface there are characteristic scaly scallops.
2. Ootheki red gerbera have a length of about 8 mm. On their surface there are distinct bands.
3. American cockroaches put off the largest ootecs. Their length is not less than 3 cm. Containers for eggs of the species represented have a rectangular shape. Surface ootek American cockroaches is divided into segments, separated by texture ribs.

How many hatching cockroaches from the egg?

So we came to the question of how many eggs can be contained in one masonry? Some species of cockroaches produce a different number of offspring:

1. Red Prusaki - from 25 to 50 embryos in the ooteka. During the life cycle, each female is capable of producing no more than 12 clutches.
2. Black cockroaches - from 12 to 18 eggs in one cocoon. During the life of the female, slightly more than 20 clutches are performed.
3. American cockroaches - 10-15 clutches, in each of which can be up to 19 eggs.

How many cockroaches hatch from one egg (ooteca), largely depends on the availability of favorable conditions for the life of young individuals. Females can carry cocoons with embryos from 2 to 6 months. In the presence of a very arid environment, lack of food, various kinds of irradiation, chemical influences, and other negative factors, the female may prematurely drop the ootheka. In this case, not all larvae will survive. Some of them do not hatch at all or will be born underdeveloped.

Do cockroaches care about offspring?

So we found out how many hatching cockroaches from one egg in different species. Now let's look at what happens to young individuals after they leave the ootheca.

The larvae of cockroaches are called nymphs. From adults, they differ only in the translucent structure of the body, modest in size, and inability to reproduce. Nymphs can be white for several days. It was from here that there were delusions about the existence of a separate species of pale mutated cockroaches.

Different types of cockroaches show the following care for the offspring:

1. Black insects discard the cocoon a few days before the birth of nymphs. The females of this species show absolutely no concern for the offspring. This is one of the factors that leads to a gradual decrease in the number of representatives of this species on the planet. After all, other insects, in particular ants and the same red Prusaki, often eat young individuals of black cockroaches that did not have time to leave the cocoon.
2. True miracles of caring for offspring are shown by red cockroaches. Female females of this species discharge ootecs only in the presence of the most favorable conditions. They do this before the immediate exit of the mature nymphs from the cocoon. Moreover, females for several hours are near the egg storage, protecting it from other insects.

Eventually

In the presented material, we examined how many hatching cockroaches from the egg. The photo of the indicated process can be seen above.

Finally it is worth noting that only one insect is born from each egg directly. As for ootecs, which are often confused with cockroach eggs, several dozen larvae can spawn from such cocoons at a time. However, ootecs are not eggs by nature, but only protective shells that protect young parasites from the adverse effects of the environment.
