Pleasley Pits - Butterflies and Dragonflies

Yesterday, in the 32 degree heat (!), I decided to have a drive over to Pleasley Pit to try and see my first dragonflies of the year and a few butterflies. 

The first species I saw was Small Blue. There weren't that many flying, but I did manage to see a few individuals and a mating pair. Other butterflies seen were: Common Blue (2 males), Brimstone (1 male) and a single Comma. One Burnet Companion and one Silver-ground Carpet (day-flying moths) was also seen.

Damselflies seen were: Common Blue, Blue-tailed, Large Red and Azure.  Two species of dragonfly: Four-spotted and Broad-bodied Chaser were also seen.

Pleasley Dragons and Butterflies

 Yesterday, the temperatures hit 23 degrees, with lots of sun and blue skies, so Jayne and I drove across to Pleasley Pit to see if there were any dragon and damselflies about. In total, we saw 5 species and 6 species of butterfly.

The first damselflies we saw were Large Red Damselflies. In total, we saw a minimum of 15 pairs "in tandem" and ovipositing. Next up, were Azure and Blue-tailed Damselflies, with just 1 of each seen. 

Two species of dragonfly were seen: Broad-bodied Chaser (1 male seen) and Four-spotted Chaser (2 seen).

After the dragonflies, we had a quick check on the Small Blues. 10+ were seen, along with 1 Common Blue,  1 Holly Blue, 1 Orange Tip, 1 Brimstone, Large White and a single Burnet Companion (day-flying moth). 

First Dragons and Butterflies

 Last week, Jayne and I went to RSPB Old Moor (see last post). Whilst there we had our first damselflies of 2024. The two species seen were: Large Red and Blue-tailed Damselfly.

Today I went to Pleasley Pit to look at the colony of introduced Small Blue butterflies. There were 6 flying around, and landing on my feet!

Whilst there, I also saw Large Red (c.5) and Blue-tailed Damselfly (1 male), but, by far the biggest surprise, was a female Hairy Dragonfly ovipositing!! I put the record on IRecord, and it appears that it's only the second record of the year for Derbyshire! In addition, it's my first record for this site.

Small Blue and Dingy Skipper - 20th May 2023

 After seeing details on social media earlier in the week, Jayne and I spent a couple of hours at Pleasley Pit searching for a colony of introduced Small Blue butterflies.

We arrived at the car park, and after walking just 200m, saw our first butterflies (they really are small!!), 3 males, one of which posed beautifully.

We walked on to the area where previous sightings had come from, where we managed to watch both males and females, including this mating pair. At one point there were 11 on the ground together!!

Whilst there, we also spotted several other species: Peacock (2), Comma (2), Orange Tip (1 male) Large White (2) and, best of all, a Dingy Skipper.

Small Red-eyed Damselfly

 I spent a couple of hours at Pleasley Pit Nature Reserve yesterday afternoon, after seeing reports on social media, of both Small Red-eyed Damselfly and Brown Hairstreak (butterfly) there.

When I arrived I went straight to the "dragonfly ponds", where I met (by accident) the person who had posted details of both species the day before. He gave me directions of where to find the damselfly, and I managed to get excellent views (about 2m away) of at least 4 males. This is only my fourth siting of this species (see here), and my first in Derbyshire. I managed to get lots of photos, but this one is my favourite as it shows the diagnostic features, separating it from the much commoner Red-eyed Damselfly.

The key identification features include a smaller size, the blue sections on top of segments nine and ten (last two segments at the end), and on the sides of segments eight (third from the end), one and two, of the abdomen, paler red eyes and a black "X"-shaped marking on the top of segment ten. One other feature, shown nicely in this photo, is the way the abdomen is held slightly up turned (Red-eyed Damselflies hold it straight when at rest).

Whilst on site, I also managed to spot several other species, including Emperor (female ovipositing), Migrant and Southern Hawker, Emerald Damselfly, Common and Ruddy Dater.

The other reason for my visit was to hopefully see Brown Hairstreak butterflies. Despite a couple of "possibles" I didn't confirm a siting (this time!) as the rain started. I did, however, see 3 Small Tortoiseshell, 1 Brimstone and 1 Meadow Brown.
