Macrosaldula scotica, also called "Rubble Hopper " in German , is a bug from the family of the bank bug (Saldidae).

features

The bugs are 4.8 to 6.7 millimeters long. The second antenna link of the type is unusually long, at least 2.2 times the length of the first link. The first limb and the thighs ( femora ) of the front and middle legs are patterned lengthways in black and white. The hemielytres are dark and have a few pale spots. In addition, the animals have short fluffing, which is more evident on the front part of the body. There are individuals with slightly shortened wings and those with fully developed (macropter) wings.

distribution and habitat

The species is boreomontane in Europe . It occurs in Northern Europe also north of the Arctic Circle and on the British Isles also in the north. In the south they are mainly found in the Alps, the Apennines and the mountains of Southeast Europe to the Caucasus and from the French Massif Central and the Pyrenees via Spain to the Atlas of Morocco. In Central Europe they are found in the low mountain ranges and the Alps from 900 to 1800 meters above sea level, but they come from the rivers that arise there to the flatlands, for example as far as the Rhine delta in the Netherlands. The species is widespread and common in the UK. Shores free of vegetation are settled with coarse gravel and rubble and sandy areas in between on slow and fast flowing waters. The bugs are also found on man-made bank reinforcements made of large stone blocks in the lowlands.

Way of life

The animals are good fliers and runners. The adults of the new generation appear from around July. These animals overwinter. In the lowlands a complete or incomplete second generation can be formed, in which the nymphs then hibernate. Apparently eggs also hibernate.
