Four-spotted Chaser - Libellula quadrimaculata
Similar to males, main difference is the shape of the anal appendages.


Prefers sites of still water consisting of lakes, ponds, bog pools, canals and dykes. Will tolerate brackish conditions. The largest concentrations are associated with acidic ponds and pools.


Males are territorial, their noisy clashes are obvious where densities are high. Readily returns to the same perch on emergent vegetation, after sparring with other males, or after short patrols along the waters edge. Copulation is short taking place in flight, only lasting for 5-20 seconds. Female oviposits by flicking the abdomen tip downwards into the water. The eggs then sink and adhere to submerged vegetation. Males may stay close by to guard females during oviposition. Larvae live among the bottom debris, then emerge after two to four years. Emergence takes place amongst marginal vegetation during daylight hours.
