Editing Aeshna isoceles (section)

==Identification==
''A. isoceles'' is one of only two brown hawkers found in Europe, the other is ''[[Aeshna grandis|A. grandis]]''. Both have a brown thorax and abdomen but ''A. isoceles'' has green eyes and clear wings and a diagnostic yellow triangular mark on the second [[Abdomen#Invertebrates|abdominal]] segment. The hindwings have an amber patch at their base. In contrast ''A. grandis'' has yellowish wings and blueish eyes. The green eye of ''A. isoceles'' stands out even in flight and in practice it is not difficult to tell these two dragonflies apart. In addition to the morphological differences ''A. isoceles'' is on the wing much earlier in the year than ''A. grandis''.
