Seven Hours at Linacre!

 Yesterday (19th), I had a couple of visits to Linacre. The first, from 06.00 - 09.30, was a ringing session, with 3 other members of Sorby Breck Ringing Group, whilst the second from 14.00 - 17.30, was a solo walk, looking for insects and carrying out this month's WeBS walk.

The ringing session was quite a quiet affair, with just 9 birds ringed. Happily, 8 of the 9 birds were juveniles, i.e. born this year, but the low number was quite disappointing, given the time of year. Hopefully, numbers will pick up, as the summer progresses. Bird caught were (new/retrap): Blackcap 1/0 (juvenile), Chiffchaff 4/0 (all juveniles), Robin 1/0 (juvenile), Blue Tit 1/0 (juvenile) and Bullfinch 2/0 (1 adult - born last year, and 1 juvenile).

By the afternoon, the temperature had risen to 22 degrees, so I went back down for a walk around the site. As you can see from the picture below, the bottom reservoir is currently nearly dry. It has been drained as maintenance work is being carried out on the overflow. As a result there were few birds there, but the exposed mud could bring in some waders perhaps.

Waterbirds see were: Mallard (42 - 40 adults and 2 juveniles), Tufted Duck (24 - all adults), Mandarin Duck (17 - all adults), Coot (1 adult), Moorhen (3 adults), Grey Heron (1), Great-crested Grebe (3 adults - no juveniles this year), Herring Gull (1 adult), Lesser Black-backed Gull (5 adults and 1 juvenile),and, the best of all, a juvenile Common Sandpiper!

Whilst on site, I also spent a lot of time (!) looking at the amazing number of butterflies and other insects present. Very conservative estimates of species seen are: Meadow Brown (50+), Gatekeeper (9), Speckled Wood (3), Comma (2), Painted Lady (6 - 5 very fresh looking individuals and 1 very tatty one!), Holly Blue (4), Green-veined White (2), Large White (1), Peacock (3), Small Skipper (1), Silver Y (1), Shaded Broad-bar (1 in the ringing site), Brown Hawker (2), Common Blue Damselfly (100+, including ovipositing pairs), Blue-tailed Damselfly (1 male), Migrant Hawker (6), Volucella inanis (2), Volucella pullecens (3), Myathropa florea (1) and Eristalis sp!

Another new species for Linacre!

 I've had a couple of 2-hour visits to Linacre this week and managed to record lots of insects, including a new species!

The first walk, on 28th, with 3 of the volunteer rangers, resulted in the new species, a queen Median Wasp, that was seen, basking on the bracken next to the middle reservoir.

Hardwick Hall - 12th July 2025

 It's been in the high 20s, low 30s this week, so Jayne and I made an early(ish) start for our walk around Hardwick Park and Hall. We walked around the ponds, and then up through the park to the hall and gardens.

Walking around the ponds, we soon spotted the first damsels and dragons of the day, with Common Blue and Red-eyed Damselflies seen. Several Emperors were also seen (minimum of 3) and a couple of Black-tailed Skimmers. 

Black-tailed Skimmer

Butterflies were numerous (which was a nice change!) with Gatekeepers being the most numerous (30+), along with Small Copper (1), Meadow Brown (20+), Large Whites, Small Whites and Red Admiral.

There were also lots of hoverflies, including a single Volucella inanis. A single Hummingbird Hawkmoth was also seen in the gardens.

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).

LINACRE LIFER!!!

It was about 20 degrees on Thursday, so I popped down to Linacre in the afternoon for 3 hours to see what was about. In the sun there were lots of butterflies in and around the buddleia in the ringing site, including: Painted Lady (8 - it's been a fantastic year nationwide for this species, and my best ever at Linacre too), Red Admiral (1), Peacock (2), Comma (1), Wall Brown (1), Gatekeeper (1), Common Blue Butterfly (3 males, 1 in the ringing site and 2 on the bank below the top reservoir. A female was also seen in the ringing site on 23rd), Small Tortoiseshell (1), Meadow Brown (1), Speckled Wood (1), Small Copper (1 on the bank below the bottom reservoir) and Large White (2). Other insects seen were: Brown Hawker (2), Volucella inanis (1), Volucella pellucens (1) and many Marmalade and Eristalis hoverflies.

Birdwise it was relatively quiet, except for the Linacre lifer in the shape of a juvenile REDSTART!!

Redstart

This bird was seen flycatching on the boardwalk, with about 3 Chiffchaffs, for about 1 minute, during a short rain shower. Luckily I managed to get this photo before it flitted off into the bushes and disappeared. I only have one other record of this species at Linacre, 2 birds reported in May 2016, so it could be a breeding species, which has been missed, or it could  just be a passage migrant. Only time, and more records will tell. 

Other birds seen were: Mallard (71), Tufted Duck (14), Mandarin Duck (29), Coot (2 adults and no juveniles!!), Moorhen (12; 4 adults and 8 juveniles), Great-crested Grebe (1 adult), Grey Wagtail (1 juvenile), Robin (1 juvenile), Swallow (2), House Martin (6) and Lesser Black-backed Gull (10 dropped in for 5 minutes during the rain).

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.

Sunny Linacre

The weather this week has been super, with lots of sun and temperatures in the low 20s, so I thought it would be a good idea to have a few hours down at Linacre to see which insects were about. I've been down twice this week, and have managed to see 9 species of butterfly, 3 species of dragonfly, 2 species of damselfly, 4 species of bee and at least 9 species of hoverfly.

The butterflies seen were: Peacock (5; 3 on buddleia by the middle reservoir and 2 on buddleia in the ringing site), Red Admiral (2 on buddleia in the ringing site), Small Copper (2 battling males on Ragwort on the wall of the middle reservoir), Meadow Brown (5 all around the site), Gatekeeper (2 at the bottom of the top reservoir),  Comma (1), Large White (10 all around the site), Green-veined White (1 male) and Speckled Wood (7 around the site).

The 3 dragonfly species seen were Brown Hawker (at least 5 flying around the site, mainly on the top reservoir), Migrant Hawker (2, flying around the bottom of top reservoir dam wall) and Common Dater (1 male basking on the boardwalk by the top reservoir on the 18th- the first record of 2016).

Common Darter

The two damselfly species seen were Blue-tailed and Common Blue Damselfly.

The bees seen were: Tree, White-tailed, Red-tailed and Carder Bee (Common, I think).

At the start of the post I mentioned I'd seen at least 9 species of hoverfly. I say at least, because I'm sure there were more there that I couldn't identify! Anyway, I'm going to write another post about hoverflies, so here's a picture of one of my favourite species, Volucella inanis to be going on with.

As well as the insects, I also saw the immature Shag again (now into it's 9th month!!), 1 juvenile Cormorant, 14 Mandarin Ducks, 43 Mallards, 7 Great Crested Grebes ( 3 adults and 4 juveniles), 1 Grey Heron, 4 Grey Wagtails, 18 Tufted Ducks, 5 Coots ( 3adults and 2 juveniles), 5 Moorhens ( 3 adults and 2 juveniles), 12 Swallows, a group of c.50 House Martins and a young Common Toad, my first adult toad at Linacre.

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.

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)
