Ants
Who knows that ants have a higher biomass than humans on this earth?
In our latitudes, the fertilized queen survives the winter. She builds a new colony every year. Queens can live for up to fifteen years and, as with bees, ants also form colonies in which only infertile females live apart from the queen. Only once a year - usually in late summer - do young winged queens and males form. While fertilized young queens look for winter quarters and most of them survive, unfertilized and male animals die.
These animals are not welcome in homes and gardens, as they build large nests in the lawn, undermine stones, spread weed seeds in the garden and, especially in spring, take care of and defend aphid colonies. Another point is the spread of plant diseases.
