Biology

Odonata species start their life as aquatic larvae or nymphs, passing through a series of developmental stages or 'stadia', undergoing several moults as they grow. This larval period can last anything between three months and ten years, depending upon the species. Before the final moult (emergence), metamorphosis occurs in which the larvae transform into the adult form. After emergence, adults undergo a pre-reproductive phase known as the maturation period, when individuals normally develop their full adult colour (7). In the dwarf damselfly, larvae grow generally over one year, but 10 to 20% do not reach emergence until their second year. The main flight period for the adult of this species is from the beginning of June to the end of July, during which time they must mate (5). Adults remain usually perched for a long time without flying and prefer the thin leaves of some sedges such as Carex limosa and C. lasiocarpa on the fringe of peaty pools and peat bogs, in order to detect any threat on each side. From time to time, they feed on small flying insects. Some isolated specimens have been found about 10 km away from their reproductive site and the species is able to colonise new water bodies. Females lay eggs (oviposit) in plant tissues, using their ovipositor to cut a slit in the tissue into which they lay their eggs.
