Two new Odanata species added to the Garden List

This month has seen two new Odonata species added to the garden list – bringing the total to six species recorded to date.

On the 2nd a single Large Red Damselfly (Pyrrhosoma nymphula) was hawking over the grassland – and by the 11th at least four individuals were present comprising two pairs in cop. on both New Pond and Bucket Pond respectively.

An immature Broad-bodied Chaser (Libellula depressa) spent the 14th patrolling the three small ponds and roosting at length on a bamboo cane standing in a nearby flowerpot. Early in the morning a teneral Large Red was drying out on the Japanese Maple (Acer cultivar) behind New Pond and later three full coloured Large Reds were present incl. a pair in cop.

The following day I found three Large Red exuvia attached to the Slender Clubrush (Isolepsis cernua) in New Pond.

Having returned from our Norway trip yesterday, I spent most of today in the back garden and saw another pair of Large Red in cop. I searched for more exuvia across all three ponds but did not find any.

Of dragons and Damsels ..

Common Darter 27th Aug 2022

A Common Darter (Sympetrum striolatum) is photographed in the garden, resting on the side of the water-butt pond. It will stay most of the morning. Later, I set about clearing the filamentous green alga from both ponds.

I remove the alga in small clumps. Wash it gently in a small tub of clear pond water, remove as many of the aquatic invertebrates as is possible, from the sticky algal grasp. Once washed the alga is left to drain on the side of the pond(s), prior to disposal.

It is encouraging to see how much motile life, exists within these ponds - aquatic worms; ramshorn and other pond snails; daphnia; chironomids; mayfly nymphs. Along with those critters that remain a complete mystery to me?

In one of the small wash cycles, I observe a couple of nymphs who are both touting three tails, they do not not look right for mayfly nymph?

Transferring them to the shallow top of a specimen bottle, we view them under the dissecting microscope, and confirm that they are damselfly nymphs.

To date we have only recorded two species of damselfly in the garden: Azure Damselfly (Coenagrion puella), and Blue-tailed Damselfly (Ischnura elegans) - so it is likely that these nymphs belong to one (or both?) of these species.

Add to this the recent discovery of the dragonfly nymph (Sympetrum cf striolatum), and it bodes well for the water-butt pond as a wildlife habitat, if it is able to attract and support these predators.


Next year, I will be looking out for exuviae, in the hope that the ponds remain suitable to bring these species to maturity.

Bragging to R on Whatsapp about the damsel nymphs, the retort is a photo of Willow Emerald (Chalcolestes viridis), a LIFER that R has just seen, at a site in Hertfordshire. By coincidence this is the second time this week, that Willow Emerald had been drawn to my attention.

S had photographed a specimen at Buchan Country Park on Thursday. So I have decided to take a good long look for it, when next in the Park.

Enter the Dragon .. (Reprise)

It has been a quiet year to date for Odanata in the garden. On the 8th of July a male Azure Damselfly (Coenagrion puella) was noted resting on the Marsh Marigold (Caltha palustris) at the water-butt pond. It was only seen that once.

On the 1st of August, a Common Darter (Sympetrum striolatum) was holding territory using the back of the garden chair as a lookout post. This encounter transpired to be an all but brief affair too, with only a single day's activity observed, before it disappeared from the garden.

Throughout this heat-wave, both small ponds have required continous top-up  and much attention has been given to removal by hand, of the filamentous green alga which threatens to completely cover the surface of the ponds.

During the course of one such clearing, I was delighted to find a dragonfly nymph (Sympetrum cf striolatum), in the water-butt pond.

Enter the Dragon

Whilst the (new) garden list has been getting longer year on year since I first started recording in August 2016 my sightings of Odonata have remained few and far between.

It took nearly two years before I got my first record - a single azure damselfly (Coenagrion puella) on the 9th June 2018. Needless to say I was more than made up to break my duck! Then, by some natural coincidence I was to get my second record of this species exactly a year later on the 9th June 2019.

This sighting was swiftly followed by a new species record on 1st July 2019 - when a single blue-tailed damselfly (Ischnura elegans) went to roost in the long grass of the "wildflower patch".

As if this wasn't excitement enough, by the end of August I was over the moon to capture the image of a male common darter (Sympetrum striolatum) as it patrolled the back garden looking for a vantage point / territorial perch .. first stopping on the handle of a hand fork, that had been pushed into the ground in order to hold down the edge of some wildflower turf .. then alighting on the blueberry bush .. where it posed obligingly for some time.




Three weeks later a second common darter has appeared , this time a female, who spent time on the miniature apple tree, allowing me to get close enough for some (almost) frame-filling shots.

Titchfield Haven - some lesser noted species, and a GYL

An afternoon's trip to Titchfield Haven NNR was rewarded with the deafening cacophony of breeding black-headed gulls, their young an assortment of ageing unfledged forms varying from brown balls of black spotted down, to the large grey youngsters that resemble waders out of the corners of your eyes. A single pair of med gulls, amongst them, the female still sitting on unhatched eggs. Avocet youngsters mimicked their parents scooping at the surface of the water, one pair with four(!) young at the water's edge.

Drifting between the hides on the northern side of the reserve, hoping for a glimpse of the GYL - we stopped at the Darters Dip bridge, watching a four spotted chaser patrol its territory - battling off usurpers - from its favourite perch on a dead stick wet ditch side.

Below in the ditch, a small shoal of chubb swam, easily disturbed by a shadow cast from, or heavy footfall on the wooden planks of the bridge. A brilliant green female damselfly - hastily identified as a banded demoiselle - as much on habitat expectations as features noted - shone amongst its duller cousins.

A solitary painted lady flighty in the wake of passing disinterested birders, failed to settle, flushing frequently before heading west along the path.

A quick drag up to the Posbrook Floods, and we were able to connect with the GYL, staring intently at a clump of rush some 40-50m away for about twenty minutes, before the bird finally appeared mid-clump like a shy actor emerging from between the stage curtains. Too far away to bother with a record shot, we watched the bird a while, as it preened, roosted did little else of note.

Burton Mill Pond - damsels on the wing

I first got sight of a damselfly on the wing at Burton Mill Pond, on the 15th of this month it was dark and very flighty and defied a positive ID. Returning today with camera in tow, I found Ca. 8 - 10 individual large red damselfly (Pyrrhosoma nymphula) hugging the waterside vegetation and hedgerow along the dam crest.

Alice Holt and Thursley Common

Out of county trip today, saw David and I heading for the Surrey heathlands in search of Lepidoptera and Odanata.

At Goose Green, Alice Holt, we watched purple emperor (Apatura iris) - with one male atop a sweet chestnut (Castanea sativa)- tussling a second male on the wing; and purple hairstreak (Neozephyrus quercus) - both species lifers for me.

Also flying ringlet (Aphantopus hyperantus), peacock (Inachis io), meadow brown (Manilio jurtina), large skipper (Ochlodes venata), marbled white (Melanargia galathea), gatekeeper (Pyronia tithonis) and silver-washed fritillary (Argynnis paphia).

Odanata interest was provided by brown hawker (Aeshna grandis) and southern hawker (Aeshna cyanea).

A goshawk (Accipiter gentilis) overhead was a complete bonus!
