Megalonotus chiragra is a bug fromthe Rhyparochromidae family . The species was not previouslyseparatedfrom Megalonotus sabulicola and Megalonotus emarginatus , so that older information about the find has limited informative value.
features
The bugs are 5.2 to 6.7 millimeters long. Like all representatives of the genus, they have a darkly colored pronotum, especially roughly dotted at the back . The thighs ( femora ) of the front legs have one long and several small teeth. Megalonotus chiragra can be identified by the long, erect hairs on the pronotum and the even curvature of the posterior margin of the pronotum. In the similar species Megalonotus emarginatus , the corners protrude at the rear edge of the pronotum and are angled sharply backwards. The rails ( tibia ) of the middle and rear legs are dark. In Megalonotus sabulicola , they are pale brown. Most animals have shortened (brachyptere) wings.
distribution and habitat
The species is widespread in the Palearctic and occurs from North Africa across the Mediterranean to southern Scandinavia and east across Asia Minor, Central Asia and Siberia to China. It is also common in North America. The species is widespread in Central Europe and particularly common in the north. It is the most common member of its genus in Great Britain and is common throughout England and Wales. Similar habitats are populated as with Megalonotus antennatus , Megalonotus chiragra , however, has a greater heat requirement, so that it is not found in damp and shaded habitats. They are often found on fallow land, ruderal sites and in cultivated land, especially on sandy and calcareous soils.
Way of life
The females lay their eggs individually in grass, herbaceous stems or moss. Sometimes at the end of July both the adults, the old and the new generation can be found together.
