Ruddy Darters

The coldest June for several years has kept dragonfly numbers to a low level as well as reducing time to go out and see then, never-the-less when the sun comes out there is still plenty of action to see.

At Wadenhoe, numbers of Scarce Chasers were good, with approximately 1 male per 10m of river bank and three mating pairs. Plenty of territorial clashes were happening due to the high male density. Banded Demoiselle numbers were lower than I expected form this time of year, with only around 200 present.

Tony Vials reported finding a female Scarce Chaser at Irthlingborough Pits last weekend, so I visited at lunchtime to try and fin more. Entering from the town side, the first section of the river showed 1 male, so I am hopeful that there are more and that colonisation has begun. I was very impressed by the new ditch on the left of the pathway. While watching a male Broad-bodied Chaser, I saw two Ruddy Darters take their first flights. The ditch showed 4 more male Chasers, a couple of Four-spotted Chasers and an Emperor. The ditch on the right is now fenced off, but is so overgrown with reedmace that it's value has declined. I worry that the same will happen to this new one as there are already signs of reedmace growth here.

I took my customary trip to Greens Norton to see the Beautiful Demoiselles. About 20 adults were in attendance including a mating pair - my first sight of this, but they just would not settle for a photo. I also retrieved an exuvia.

Southern Hawkers and Common Darters appearing

My planned BDS field trip to Yardley Chase was a washout with constant drizzle all day. Five brave enthusiasts put the rain out of their minds and joined me for the day hoping to catch sight of a perched Downy Emerald. While no Emeralds were found, we did recover a few exuviae to the delight of Trish who needed one for her collection. While we braved the weather, so did a handful of emerging Four-spotted Chasers. One attracted much interest to the photographers (photo below) because we found it protecting itself under an Iris leaf in a very photogenic position. We found several more exuviae, including four Southern Hawkers, the first of the year.

Returning to the Chase, I found a few Downy Emeralds at territory but numbers appear to be well down compared with previous years, perhaps due to poor weather during their main emergence window.

White-legged Damselflies are now in good numbers on the Ise, with adults recorded at Burton Latimer Pocket Park, Harrowden Lane and south Wellingborough.

At Titchmarsh Nature Reserve, Scarce Chasers are  now at territory and Black-tailed Skimmers are appearing along with the usual Damselflies and Demoiselles. Emperors are also cropping up at territory after their relatively short maturation time.

I took a break from the Sunday ironing and popped across the road to Stanwick Lakes. The ponds and pits around the Visitor Centre are great places for Black-tailed Skimmers, so I hoped to find a few emerging. Walking clockwise around the large gravel pit, close to the water, I must have disturbed over 2000 emergent Common Blue Damselflies. There were similar numbers around the other waters close to the centre. too I never tire of this experience and it always makes me wonder how many there actually are and how many these pits support in a year - 10,000+ maybe? Not forgetting the hundreds of Red-eyed Damselflies and Blue-tailed Damselflies! I only found one emergent Black-tailed Skimmer though - they are only just starting to emerge to I am sure there are more to come in the next few days.

In the afternoon, I took a walk along the Nene at Wadenhoe. Fewer than expected Banded Demoiselles were present along the river, with good numbers of Red-eyes on the lily pads. I counted around 15 Scarce Chaser, including one pair incop and around three emergent adults. All the males showed signs of the immature orange colouration through their blue pruinescence. I walked up to Achurch and through the rides to Lilford, hoping to find more immatures. Only one immature male was around along with a male Hairy Dragonfly.

White-legged Damselflies and others

On the River Ise at Burton Latimer and Finedon, White-legged Damselflies are now present. All of the adults I saw were immature (no blue males) so must only have emerged in the last few days. In the immature stage, males and females look similar from a distance but up close the differences become apparent. Plenty of Banded Demoiselles around too.

I visited three sites in one day to try and catch a good range of species. Starting off at Yardley Chase, Downy Emeralds were showing in good numbers although none performed well enough to capture in flight shots except an ovipositing female. While watching her, I found a pair in cop which is something I have never seen before. Although the light wasn't in a perfect direction, I was able to get a shot that I am more than happy with especially as this is not commonly seen, mostly occurring high in the tree tops. There were plenty of Four-spotted Chasers around too and many ovipositing pairs. When the female oviposits, the male flies around her in a protection mode to fight off other males. This gives the best opportunities for in flight shots. Unfortunately, this was when the sun went behind a cloud which caused my camera's ISO to shoot up hence increasing image noise. A pair of Broad-bodied Chasers made an appearance and ovipositing ensued. I still have a few spaces on my field trip here for 13 June so if you would like to come along, please contact me. This is a permit only site so there is no access to the public (the site is also locked!). 

At Maxey Pits, I saw fewer Variable Damselflies than usual, mostly males and 1 female, with one pair fleetingly seen in tandem. I visit this site about once per year around this time, so I haven't hit the end of their season and hope this is just a blip and doesn't indicate the start of a decline in the species. Plenty of Common Blues, Blue-tails and Azures.

My final stop was at Wadenhoe looking for Scarce Chasers. None were in evidence, but by  now it was 1600hrs and a bit breezy so they may have gone to roost for the evening. What did surprise me was the number of Red Kites around. I often see 4-5 here, but today there were around 30 (I did try to count) and I wondered whether they were breeding and the young had just fledged. They were clearly visible over the manor house from the Mill car park.
