Consultancy and Environmental Education: The seven-point ladybug

We've all picked up some of these nice insects, and we're glad to see them again every year when they start reappearing in the spring. And is that Ladybugs are a symbol of nature, apart from some insects very beneficial in the control of some pests, much more effective and ecological than pesticides.

The ladybird that everyone associates with this group of insects, is the seven-point, scientifically called "Coccinella septempunctata" and belongs to the family Coccinellidae < / i>. This is the ladybug what else we can find in Europe, although there are other types. The elytra (these partially-hardened wings that serve as protection for the lower wings) of this insect are red and have three black spots in each one of them and another in the place where they are united, which is divided between the two.

Because it has these seven points since it is a mottled species, it is often called the "Septen" name of the number seven in Latin or "Punctata" meaning mottled. It is clear that the features that clearly differentiate this small insect that is almost always received with sympathy, being in some cultures symbol of good luck.

The size of these insects is quite small, we have all seen how picking them without damaging them requires a lot of subtlety, measuring from 5 to 8 millimeters in length. They have an oval shape and are very bright, always presenting some vivid colors with their characteristic spots. In other species of Coccinellidae can also be seen the colors orange and yellow part of the better known, red. And they can also present other schemes like dashes instead of points in their elytra.

And it is not too far from the reality of ladybugs the subject of poison, some of them are really toxic to other small species such as lizards or small birds, and especially ants. We have all seen when we have caught a ladybug as it has tried to protect itself by excreting a yellow liquid. A liquid that many people associate with that ladybug has "done their needs", but that really expels to try to defend themselves. The truth is that they are totally harmless to humans, and should not be afraid of us, especially because it provides us with a very important cleaning service for our plants.

This is precisely one of the most curious of the Ladybugs. They are excellent planters at the service of humans and play a very important biological control function in certain crops. The ladybirds feed on aphids, also called aphids, and they do it with a lot of insistence because a single ladybird can get to consume over a summer more than 1000 of these insects. They are much more effective than all natural insecticides. Such is the need for the ladybirds of these insects, that the females will only lay the eggs in places where they know there are and there will be aphids.

It is at this point that something curious happens. Ladybugs sometimes enter into confrontation with the ants for this source of food, and it is not that the ants also eat them, but that they breed them as humans do with the cattle, taking care of them and protecting them from the threats to segregate a juice which they use in their anthills. When the ladybirds find one of these ants managed by the ants, they usually fight for this curious natural resource.

There are some facts about these little insects that are really curious and may make us see them differently the next time we find one and stop to look at it.

One of these curious facts is that a female ladybug, throughout its life gets to put more than a million eggs. This is a large amount considering that the life expectancy of this small insect is 2 to 3 years. Another is that the ladybugs only feed in spring and summer, and during the winter they eat practically nothing, surviving this season only with the fat stored in their body. And the last thing we want to point out is that the sense of smell in this insect is not in the area of ​​the head but rather in the legs, characteristic of some groups of insects.
