Campylosteira verna is a type of net bug that is widespread in Europe and various Mediterranean countries. It is one of the smallest Central European net bugs.
features
Campylosteira verna is about 1.6 to 2.3 mm long. It is brown to red-brown in color, the top is glabrous and shiny. The head is about as long as it is wide, with two short tylus spines on the tylus or frontal wedge, next to the base of the antennae. On the trapezoidal pronotum, the genus lacks the vesicular distended cervical vesicle that is present in most genera and which partially covers the head. The third antenna segment is elongated and slender, almost three times as long as the fourth, somewhat broader; it is not, as in many related genera, covered with a broad border of protruding rods or short bristles. The three keels on the upper side of the pronotum slightly diverge towards the front, the widened side panel has two rows of cells or meshes towards the front and only one row towards the rear. The lateral edge of the pronotum is straight when viewed from above, not indented.
Mostly, as in the figure, brachypter bugs are found (i.e. with reduced hind wings), only rarely do these net bugs have fully developed wings, i.e. they are macropter. In the Brachypterian bugs, the forewings often gape a little apart at the seam when in rest position (as can be seen in the figure), they only overlap at the tip, if at all.
Distribution and way of life
The species is widespread in Europe, north to England and south Scandinavia, south to the Mediterranean, east to the Caucasus. It is also widespread in Germany and Austria, but is relatively seldom found due to its small size. Sometimes animals of this type are found in larger numbers in soil samples, so they can be quite common locally. They usually occur in dry, warm or moderately humid places, provided there is moss. Little is known about the way of life; it is assumed that the animals suckle on mosses or lichens. However, the species is not always tied to mosses; it is also found in plant litter.
The bugs hibernate as adults (adults) and can therefore be found very early in the year (Latin species name: "vernus" = belonging to spring), copula and oviposition take place in April and May, new adults appear from July or August .
Taxonomy and systematics
The species was first described as Tingis verna by Carl Fredrik Fallén from Sweden, it is, by subsequent decision of the ICZN, type species of the genus Campylosteira . Synonyms are Campylosteira brachycera fever, 1844, Campylosteira falleni fever, 1844, Campylosteira sinuata fever, 1861. The var. Latipennis Horváth, 1892, which has been distinguished by some authors , is no longer differentiated today. The genus belongs to the subfamily Tinginae within the net bugs, it includes, depending on the taxonomic view, a good 10 to just under 20 species. Contrary to previous beliefs, it is the only Central European species of the genus, other species are to be expected in the Mediterranean region.
