The last few days have been sunny and pleasantly warm, even quite hot at times!
So, making the most of the good weather, I’ve been out and about taking photographs of the newly emerging wild flowers, butterflies, damselflies and dragonflies. It’s been noticeable over the last week or so, with the warmth of the sun (and a well watered spring!!), how the the countryside has taken on a new lushness of growth and colour.
The ‘early’ damselflies and dragonflies have started to take to the wing now…
Banded Demoiselle (calopteryx splendens)….The males are very territorial and will fight off anything that flies into their patch. They also ‘court’ the females by flicking their wings open and performing an aerial dance in front of them.

Azure Damselfly (coenagrion puella)….One of the two most common blue damselflies, confusingly the females are mostly green with black on top of the abdomen.
Male
Large Red Damselfly (pyrrhosoma nymphula)….One of the very first to emerge in the spring and quite widespread but avoids fast flowing water. The males, which appear in greater numbers than the females, are aggressive and very territorial.
Male
Blue-tailed Damselfly (ischnura elegans)….Another quite common damselfly. always found close to water, unlike some of the other damselflies which can roam widely. The females come in a variety of colours from green through violet to blue.

When damselflies and dragonflies emerge as adults they first go through a stage where they are known as tenerals. During this stage which, depending on the species, can last from a few days to a few weeks their wings remains ‘milky’ and reflective and their flight is weak and fluttery. And to make identification a little difficult they lack the colouring of the adult and appear pale and drab.
How the dictionary calls it…
Ten´er`al
(Zool.) Of, pertaining to, or designating, a condition assumed by the imago of certain Neuroptera, after exclusion from the pupa. In this state the insect is soft, and has not fully attained its mature colouring.
Common Blue Damselfly (enallagma cyathigerum)….The most common and widely distributed of our native damselflies. Found in association with both still and flowing water, although immatures can be found some distance away from water bodies.
Teneral Male

Teneral Female
Females, unlike other blue damselflies, can be identified by the presence of a ‘spine’ in front of the ovipositor, under section 8 of the abdomen. (it can be clearly seen in this image)
Adult Male
Red-eyed Damselfly (erythromma najas)….found only in the southern part of the country it prefers large bodies of standing water with lots of floating vegetation, especially water-lilies where the male likes to ‘rest’ on the leaves while waiting for an opponent to come into range when they’ll fight over the territorial rights.
Teneral Male
Hairy Dragonfly (brachytron pratense)…. The smallest of our resident hawkers and the earliest to emerge in early May and June. Found in the southern parts of the UK, where the male can be seen patrolling over clear unpolluted and well vegetated water as it searches for females while fighting off any interlopers.
Male
Four-spotted Chaser (libellula quadrimaculata)….Widespread over most of the country and readily identified by the ‘four’ wing spots. The male can be seen perched on a single stem of vegetation as it waits to see off any intruder, or to intercept a passing receptive female when they will briefly mate while on the wing.
