features
The dragonflies reach a body length of 39 to 46 millimeters. The wingspan is about 55 to 65 millimeters. At the base of the hind wings there is a small yellow basal spot that disappears with age. The pterostigma is strikingly yellowish; The specific epithet chrysostigma , which is formed from ( Greek ) “chrysós” (gold) and “stígma” (sign or brand), also refers to this wing mark. On the sides of the thorax there is a black-edged, cream-colored stripe that gave the Rahmstreif blue arrow its German name. The males are blue, the abdomen is slightly waisted. The basic color of the female is brown, here several thin stripes go through all segments. The species resembles the small blue arrow ( Orthetrum coerulescens ), the southern blue arrow ( Orthetrum brunneum ) and the Gelbader blue arrow ( Orthetrum nitidinerve ), the male can be distinguished from these by the waist of the abdomen between the third and fourth abdomen segment .
