Linacre - 30th June 2024

 It hasn't been a great summer for butterflies so far, but a walk around Linacre this morning got me two new species for the year, along with a new moth and a record count of Common Sandpipers.

The two new butterflies were: Meadow Brown and Ringlet, with 2 of each species seen, on the dam banks and the ringing site respectively.

Two moth species were identified: Latticed Heath (2nd record of the year) and a Shaded Broad-bar (1st record of the year).

Birdwise, it was a decent morning too, with some very good post breeding counts, a new (for the year) breeding record and, as already mentioned, a new high record of Common Sandpipers. Birds seen were: Mallard (114 adults and 4 broods of 1, 3, 5 and 1;124 birds in total), Mandarin Duck (62 adults and 3 broods of 5,1 and 1; 69 birds in total), Tufted Duck (26 adults), Grey Wagtail ( 7 birds; 2 adults and 5 juveniles), Grey Heron (1),  Moorhen (3 adults - no young!), Coot (1 adult and 3 juveniles), Common Sandpiper (3 flew from the wall on the middle reservoir - my first ever record of more than 1 bird - possible breeding?), Lesser Black-backed Gull (1), Kingfisher (1), Swift ( a nice record of 7 birds over the middle reservoir), Swallow (1 bird!), Common Buzzard (1), Skylark (1 singing), Chiffchaff ( 5 singing), Blackcap (6 singing), Garden Warbler (1 singing),  Great-crested Grebe ( 12 birds; 6 adults and 2 broods of 2 and 4) and Little Grebe (1 juvenile on the middle reservoir - first young of the year).

Linacre Butterflies - 18 species!!!

The weather forecast for this morning was dry and sunny (!!!), so I spent 5 hours (8.30am - 1.30pm) on site to see what I could see. As the title of today's blog shows, it was a very well spent few hours. The total of 18 species must be my best ever, and included four brilliant species: White-letter Hairstreak, Purple Hairstreak, Silver-washed Fritillary and Dark Green Fritillary. In addition, I recorded 2 new species for the site, an Emperor dragonfly and a Hummingbird Hawkmoth!

The list of species seen is: Peacock (2), Red Admiral (7), Meadow Brown (c.20), Gatekeeper (7), Ringlet (1 very tatty individual), Small Copper (1 on the dam wall of the top reservoir), Small Tortoiseshell (3), Large White (5), Green-veined White (2), Speckled Wood (1), Comma (6), Holly Blue (1), Common Blue (1 in the ringing site), White-letter Hairstreak (1, by the bridge on the top reservoir, at 10.30am), Purple Hairstreak (1, in oaks by the bottom reservoir, at 12.45pm), Silver-washed Fritillary (3; 1 male and 2 females), Dark Green Fritillary (1 in the ringing site) and Small Skipper (c.5, in the field beyond the top reservoir).

 3 species of day-flying moth were also seen: Shaded Broad Bar (2), 6-spot Burnet Moth (1) and Hummingbird Hawkmoth (1 in the ringing site - a site first). 

4 species of Dragon/Damselfly were present: Brown Hawker (1, including 1 ovipositing in the bottom reservoir), Emperor Dragonfly ( 1 on the middle reservoir, a first site record for me), Common Blue and Blue-tailed Damselflies.

Hoverflies seen were: Marmalade, Volucella pellucens , Myathropa florae and Eristalis sp.

Two species of ladybird were seen: 7-spot and Harlequin.

I think there might have been some birds around too (!), but I didn't do a full count. Instead here are a few of the "best": Swallow (6), House Martin (2), Canada Goose (2 on the top reservoir), Buzzard (2 adults), Stock Dove (1 by the muck heap by the main entrance), Lesser Black-backed Gull (1 adult), Willow Warbler (1 very yellow juvenile bird by the top reservoir) and Chiffchaff (1 singing and lots of "wheeting").

Volucella zonaria at Linacre - 17th August 2021

 I had my forst visit to Linacre since betting back from Cornwall, on Tuesday. It was a very grey, overcast day, with a maximum of 16 degrees and frequent drizzly rain! Thankfully, there were a few breaks in the  cloud, which allowed me to see a few insects, including  a new species for me at Linacre - Volucella zonaria!

Volucella zonaria is a species of hoverfly that has been extending its range in Britain over the last few years. I've recorded it in Derbyshire before (at Hardwick Hall), but Tuesday's sighting was my first at Linacre. 2 individuals were seen, along with two other Volucella species; Volucella inanis and Volucella pellucens (no photo).

Other insects seen were: Red Admiral (1), Meadow Brown (1), Wall Brown (1 male ), Common Blue Butterfly (1 male), Green-veined White (2), Large White (1), Peacock (1),  Shaded Broad Bar (1), Straw Dot (1) Yellow Shell (2) and Eristalis sp (hoverfly).

Birdwise, it was quite quiet, but the following species were noted: House Martin (4), Common Buzzard (1 heard), Mallard (69), Mandarin Duck (40 adults and 2 ducklings), Tufted Duck (25 adults and 1 juvenile),Coot (8 adults and 1 juvenile), Moorhen (11 adults and 5 juveniles), Great-crested Grebe (3 adults and 4 juveniles, 2 each on the middle and bottom reservoirs), Grey Wagtail (3 adults and 2 juveniles), Chiffchaff (wheeting heard, and 1 bird seen in the willows by the boardwalk) and Lesser Black-backed Gull (9; 5 adults and 4 juveniles, including 1 that was begging for food - Chesterfield-bred?)

Shaded Broad-bar and Tawny Owl

 I popped down to Linacre this afternoon to fill the feeders for a ringing session. It was 24 degrees when I arrived at 3.45pm and very sunny. As I walked down to the feeders, I spotted my first Cinnabar moth caterpillars, along with two Shaded Broad-bar moths, Soldier beetles, Swollen-thighed beetles, a male Blue-tailed Damselfly, several Common Blue Damselflies and a single Black and Yellow Longhorn Beetle.

Shaded Broad-bar

When I got to the feeding station I  spotted something perched low on one of the trees. I couldn't quite tell what it was, as it was preening and had its face down. Luckily, it hadn't seen me, so, as it looked up, I managed to get this photo and saw that it was a juvenile Tawny Owl - lovely and a great breeding record!

Linacre - 12th August 2020

 The temperature was a cracking 27 degrees again today, so I decided to have a couple of hours down at Linacre to see which insects I could see. I started off in the ringing site and saw 4 Gatekeepers, 1 Comma, 2 Peacock, 2 Small Coppers, 1 Red Admiral, 2 Silver Y moths, and 3 Shaded Broad Bars.

Small Copper

Walking around the reservoirs, I added Common Blue Damselflies (including pairs ovipositing), 4 Brown Hawkers (my first Linacre record of 2020), a couple of male Blue-tailed Damselflies, and, very nicely, a male Banded Demoiselle flying over the top reservoir (my first Linacre record since 2015, and only my second ever record here). Another hawker, possibly Southern, was seen hunting along one of the paths by the middle reservoir. 

There were plenty of hoverflies around the site, including 1 Volucella pellucens a.k.a. Great Pied Hoverfly, and a single Myathropa florea a.k.a. "Batman hoverfly".

Myathropa florea

Birdwise, it was quite quiet, as is to expected, but I did have 2 Black-headed Gulls on the bottom reservoir (a very unusual August record), 11 Great-crested Grebes (2 family parties with 4 and 3 chicks, and 4 adults) and 2 Kingfishers on the bottom reservoir.

Linacre Insects - 6th August 2019

Yesterday morning I went down to Linacre to do the final check of the nestboxes (more of that in another post), and afterwards spent another 3 hours walking around the site recording the insects (and a few birds!).

It was pretty sunny all the time I was there (up to 22 degrees by the time I left), and there were a good number of insects to see. First up the dragonflies and damselflies. The most numerous species, as always, was Common Blue Damselfly, with 20+ seen, including 2 mating pairs. Two male Blue-tailed Damselflies were also seen, along with 3 Southern Hawkers and 5 Brown Hawkers.

Butterflies were also present in good numbers, including a new species for me at Linacre: Peacock 20, Ringlet 2, Large White 1, Small White 1, Green-veined White 4, Gatekeeper 6, Meadow Brown 7, Small Copper 1, Red Admiral 2, Comma 1, Painted Lady 5, Speckled Wood 1, Small Skipper 1, Narrow-bordered 5 spot Burnet moth (1 mating pair), Cinnabar Moth caterpillars, Shaded Broad Bar (1) and Wall Brown 1 female in the ringing site- my first record for Linacre!

Hoverflies seen were: Volucella inanis (4), Volucella pellucens (2), Eristalis sp and Myathropa florea (1). Other insects were: Black and Yellow Longhorn Beetle (1), 6-spotted Ladybird (1), Tachinid flies,  Common Carder, White-tailed and Red-tailed Bumblebees, 

Linacre July WeBS and insects

This month's WeBS count didn't get done earlier in the month as everyone who normally helps out was busy doing other things. Today was the first opportunity I'd had to do it, so here are the results of a slightly belated count: Mallard (42, all "adults", non obviously young), Tufted Duck (20; 14 adults and 6 juveniles), Coot (8; 3 adults and 5 juveniles), Moorhen (7; 3 adults and 4 juveniles), Grey Heron (1), Great-crested Grebe (1 adult and 2 juveniles on the middle reservoir, no sign of adults or juveniles on the top reservoir), and Mandarin Duck (5). No sign of any Little Grebes again. They don't appear to have bred here this year- the first blank year since recording began in 2006!

The weather was great today (21 degrees and sunny), so as well as the birds, I also spent some time looking at the insects again. There were good numbers of butterflies, hoverflies, dragonflies, damselflies, moths and bees.

I recorded 9 species of butterfly (Gatekeeper, Meadow Brown, Green-veined and Large White, Small Skipper, Small Tortoiseshell, Small Copper, Peacock and PURPLE HAIRSTREAK). The last species was the best, simply because it was my first Linacre record of 2014, and also because I managed to get a photo as it fed on a Thistle.

Purple Hairstreak

 

The two moth species I saw and identified today were both new for me at Linacre. Both were moths that are easily disturbed from the ground, namely Brown China-mark and Shaded Broad-bar.

Brown China-mark

 

Brown China-mark is a common species throughout the UK, but is quite unusual in that its larvae are entirely aquatic! See here for more details.

Shaded Broad-bar

 

Shaded Broad-bar is also a very common species. Details from UK Moths here.

 

Hoverflies were also present in good numbers, and included another new species for me at Linacre, Volucella inanis.

Also present today were Brown Hawker dragonflies (5+), Common Blue Damselflies (10+) and 3 species of bumblebee (Red-tailed, White-tailed and Common Carder)

Avenue Moths and Butterflies

In my last post I reported on a successful ringing trip to the Avenue Washlands in Chesterfield. Whilst there we also had time to look at the insect life of the site, so here are a few pictures and thoughts.

First up is a species of burnet moth, most likely Narrow-bordered Five-spot Burnet Moth.

Mating Pair

 

There is another species of moth called a Five-spot Burnet, but, according to the UK Moths website, the Narrow -Bordered species is much more common and widespread.

 

Another moth species seen in the grasslands was the Shaded Broad-Bar.

 As well as the moths, we also recorded a couple of butterfly species: Ringlet (10+), Meadow Brown and a new froghopper species, which I believe is a Common Froghopper (Philaenus spumarius).
