red traffic light, deceitful of enemies

  • The scientific name of the insect that we present today explains, among other things, that it is red (not completely) and has no wings. They are not both wrong, but red is not their only coloration, and it has also had wings, but their size is very variable between some grains and others, and since they have some very small ones, they can not fly.
Iñaki Mezquita Aranburu

This fast insect can be found from Europe to China and in North and Central America. Since the influence of temperature on its metamorphosis is very high, it has not expanded in northern Europe (Scandinavia) until a few years ago.

In the spring it is easy to see them racing intensely in some parts of the village, on walls and roads. Often grouped together in large groups, sometimes with the couple united from the abdomen, unable to decide where to go, the procreation turned into a ridiculous competition like a sokatira.

His life cycle lasts two or three months. Of these, he spends a week or so in the egg phase, and it takes half a month or so until he passes the larval phase and becomes an adult. As noted, these ranges can be lengthened or shortened considerably depending on the temperature. The size of the eggs is also very variable, and the size of the larvae extracted from them usually depends on them. Considering that larvae can be cannibals, it is easy to see which ones will emerge victorious...

The temperature conditions the surface of the black coloration, i.e. the colder it is, the more widespread the black coloration is. We have mentioned several times in this section about coloring that nature has its own code to indicate the danger. Red, yellow, orange and black colouration indicate the risk. Of course, humans have also used this code, although sometimes we are not aware of the origin of these colors. That’s where we have traffic lights, traffic signs, zebra tracks (originally yellow were the white or red stripes today), yellow or red lifeguard uniforms (like firefighters). In the case of this insect, however, the coloration only serves to confuse the enemies, since the animal is completely harmless to us. There are a few isolated cases where lettuce and cauliflower have started in the face of their food shortages, but in no case does it happen often or at least.

Among the hemipterans there are insects that look very similar, but instead of being herbivores they are carnivorous and feed on insects like Pyrrhocoris, like some of the Reduviidae family (which have to bear the attractive name of “killer bedbug”...), but they have nothing to do with our protagonist today, even if they are hemipterans like him.
