Nabis ericetorum (also known as the heather sickle bug ) is a species of bug fromthe sickle bug family (Nabidae).
features
The bugs are 5.7 to 6.8 millimeters long. They have rather dark, reddish-brown hemielytres and a generally reddish abdomen. As with Nabis rugosus , the dimensions of the pronotum are 1.6: 1.5 (width: length). The second antennae is about as long as the pronotum is wide. The bugs have mostly regressed (brachyptere) wings, with the hemielytras ending just before the end of the abdomen. However, it is not uncommon for individuals with fully developed (macropter) wings to exist. These animals, if they are untypically pale, can be confused with Nabis ferus and Nabis pseudoferus .
Occurrence and habitat
The species has its distribution center in the climate area influenced by the Atlantic and occurs in northern, western and central Europe and east to central and northern Russia. In the Mediterranean area, it occurs only on the Iberian Peninsula. It occurs everywhere in Germany, but becomes much rarer towards the east and south. In northern Germany it can be common in cheap places. In Austria, the species is particularly widespread in the west and south, but rare everywhere. It rises in the Alps to around 1000 meters above sea level.
Be settled Calluna -Locations where both the nymphs , and the imagines are well camouflaged by their color. The species can be found both on dry Calluna heaths with sandy soils and in moist moor heaths.
Way of life
Nabis ericetorum lives on the ground and in the dwarf shrub layer and feeds unspecifically on various prey, such as butterfly caterpillars, the larvae of the heather beetle ( Lochmaea suturalis ), cicadas such as the heather leafhopper ( Ulopa reticulata ) and various bedbugs such as Orthotylus ericetorum . The overwintering takes place as an imago, whereby the animals can sometimes become active during the winter. Mating takes place from September and from April. The females pierce their eggs mostly in the first half of May in the stems of grasses, but probably also in heather ( Calluna vulgaris ) and bell heather ( Erica tetralix ) a. The nymphs can be observed from the end of May to September, adult bugs appear all year round, with the overwintering animals having largely disappeared from mid-July. The adults of the new generation appear from around mid-August.
