Silver-studded blue, female (plebejus argus/heideblauwtje). A butterfly of mixed heath habitats.
With closed wings there is little blue to be seen in this butterfly. Only here and there a touch of cyan is visible. The male, however, make one understand the origing of the species' name. The underside of its wings is light blue with flecks, the upper side is a deeper blue. Young specimen are also equipped with a light gray fringe edge. The English name, silver-studded blue perfectly reflects that attribute.
This species has figured out a clever way to increase the chance of offspring. By secreting a sweet substance ants are attracted and tempted to build a nest around the doll of this butterfly. The ants protect the dolls and later the caterpillars against predators.Het butterfly is about 1.5 centimeters and during daytime pretty mobile. By evening it is easier to catch them in a picture.
