Linacre Insects - 13th July 2025

 After the ringing session on Sunday, I stayed on at Linacre to enjoy the sunshine and go looking for some insects. I wasn't disappointed, and managed some very good numbers of butterflies (17 species, including a new one!), 3 new moths, 1 new ladybird species, 4 species of odanata and lots of hoverflies and bees.

First the butterflies. Species seen were: Purple Hairstreak (2, maybe up to 4 seen on oaks below the bottom reservoir on 12th), Meadow Brown ( a minimum of 32), Gatekeeper (9), Peacock (2), Large White (13), Small White (3), Green-veined White (6 feeding/drinking on mud on the top reservoir, Comma (7), Painted Lady (1 in the ringing site), Small Copper (2), Small Tortoiseshell (1), Speckled Wood (2) Ringlet (1), Red Admiral (1), Holly Blue (1 - my first Linacre record of the year), a single Brimstone (my first Linacre sighting this year), and the brand new species, Essex Skipper (seen feeding with a 6-spot Burnet moth).

A couple of 6-spot Burnet moths were also seen in the field by the top reservoir (second record for Linacre) and a single Cinnabar Moth caterpillar was also spotted.

Odanata (dragonflies and damselflies) were represented by the first Brown Hawkers of the year (3), another hawker species (Migrant or Southern), a single male Blue-tailed Damselfly and 20+ (minimum) Common Blue Damselflies, including several pairs "in cop" (mating).

The new species of ladybird seen was a 14-spot, found on one of the ringer's hats!! A single Black and Yellow Longhorn Beetle was also found in the ringing site.

Last, but not least, a single Greylag Goose was seen on the top reservoir.

Linacre Insects - 3 new species!

 The summer of 2024 has, so far, been pretty awful weather wise, with very few periods of dry, warm weather. Today, the temperature managed to drag itself to 17 degrees (!), and there were a few sunny spells, so Jayne and I had a couple of hours at Linacre, and managed to find 3 new species!!!!

Although it was sunny, the number of insects seen was still pretty low, but it did, at least, have a few new records for the year, along with the new ones. Firstly, we spotted Common Blue Damselflies (c15), followed by 1 Speckled Wood, Swollen-thighed Beetles, Red and Black Froghopper, 3 Green-veined White, 1 Volucella pellucens (Great Pied Hoverfly), Eristalis sp, 1 Myathropa florea, 1 male Sericomyia silentis, 1 Mayfly sp, 3 Cinnabar Moths, 1 Latticed Heath and White-tailed and Common Carder Bumblebees.

The three new species that we saw today were: 1 Speckled Longhorn Beetle, an Agapeta hamana moth and a Orthotaenia undulana moth!

Linacre Insects - 22nd July 2023

 It stopped raining for an hour this afternoon (!), so I popped down to Linacre to see what was about. I only walked around the bottom reservoir, before the rain started again, but I did manage to spot a few insects and birds.

Insects seen were: Meadow Brown (3), Green-veined White (1), Marmalade Hoverfly, Volucella pellucens (3), Cinnabar Moth caterpillars,  Silver Y moth (2), Soldier Beetles , White-tailed, Common Carder and Red-tailed Bumblebees, and Common Blue Damselfly (1m).

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.

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 WeBS - 11th July 2020

On Saturday, I walked around all three reservoirs for this moth's WeBS count. Highlights for me were a pair of Great-crested Grebes with 4 well grown youngsters (and another pair on a nest), and my first Linacre Oystercatcher record since 2018, when 2 flew over the top reservoir calling.

Totals for all waterfowl were: Mallard (72), Moorhen (11; 8 adults and 3 juveniles), Coot (5; 3 adults and 2 juveniles), Tufted Duck (17; all adults), Lesser Black-backed Gull (1 adult), Grey Wagtail (4), Cormorant (1) and Mandarin (19; 15 adults and 1 brood of 4 ducklings).

Other birds seen and heard were: Swallow (12), House Martin (2), Stock Dove (heard), Chiffchaff (4 singing) and Blackcap (1 singing).

After the WeBS walk, I had an hour in the ringing site, where I saw 1 Ringlet, 1 Red Admiral, 1 Tree Wasp, a Marmalade Hoverfly, a Sphaerophoria scripta (Hoverfly) and 1 Meadow Brown. The first Cinnabar Moth caterpillars of the year were on Ragwort by the top reservoir.

Linacre Insects - 30th May 2020

I was down at Linacre this morning, checking the nestboxes and ringing some of this year's pulli (more on that in a future blog). With the temperature being around 19 degrees whilst there, I also managed to get some good insect records, including a new species for me at Linacre.

Insects seen today were: Large Red Damselfly (1 male), Common Blue Damselfly (c5 males), Blue -tailed Damselfly (1 male, the first Linacre record of 2020), Broad-bodied Chaser (1 female, my first Linacre record since 2014!), Swollen-thighed Beetle, Red and Black Froghopper, Cinnabar Moth (1), Silver Y moth (1), Silver-ground Moth (1), a long-horned moth, Nemophora degeerella, bees including Tree, Red-tailed and Common Carder,  and a couple of yet-to-be identified micro moths.

Broad-bodied Chaser

The new species was Britain's largest species of Crane fly, Tipula maxima. It was very big indeed! Apparently, it can have a leg span of up to 100mm.

Linacre Nestboxes, Birds and Insects

I was able to get down to Linacre on Saturday to check the nestboxes for the first time this season. I walked around all three reservoirs and checked 87 boxes. In total, I found 37 boxes with active nests in them; 33 were either Blue or Great Tits, but there were also 2 Pied Flycatcher nests, 1 Wren nest and 1 Nuthatch nest. There were also 3 singing Pied Flycatchers, which is the highest count I've had, since the first ones were recorded in 2008. All nests are being monitored for the BTO's Nest Record Scheme.

Whilst on site, I also had a look for any insects that were active. I didn't see any butterflies, but I did spot this adult Cinnabar Moth that was emerging on a fence and a Scorpion Fly.

I also managed to see the first ducklings of the year. There were two broods of Mandarin Duck, 7 and 4, and one brood of Mallard with 3 ducklings.

The best sighting, however, was my first ever sighting of a Grass Snake. I spotted one basking on a stone wall by the bottom reservoir. Unfortunately, I only managed a quick photo before it slid off, into the wall. I did, however, manage to spot a "sloughed" skin in the same spot.

Spot the snake!!

Linacre Insects - 1st June 2019

It was 20 degrees yesterday afternoon, so I went down to Linacre to have my first proper look for insects. I'm very glad I did, as I ended up recording 4 species I'd not seen before!

The first "new" species was a micro moth, Endothenia sp. Unfortunately, this moth can't be identified to species level without dissection (!), so it will have to remain just Endothenia sp!

Endothenia sp.

The second species was a macro moth, Brown Silver-line, which was seen in the ringing site.

The 3rd species is a beetle with the great name of Swollen-thighed Beetle! You can see how it gets its name in this photo.

The 4th and final new species was a Blue Lacewing.

Other species seen included; Red-tailed Bumblebee, Common Blue Butterfly (1 female), Comma (1), Cinnabar Moth (4+), Orange Tip (1 male), Silver Ground Carpet, Common Green Shieldbug, Common Blue Damselfly, Red and Black Froghopper, Harlequin and Black and Yellow Longhorn Beetle.

Linacre Insects - June 2018

This is my first post of 2018 about the insect life that can be found at Linacre. I had a visit on 1st June when it was a lovely sunny day. I spent some time walking around the ringing site and then walked up to the top reservoir.

During the visit I recorded 3 species of damselfly: Blue-tailed, Common Blue and Large Red. The first 2 species are common around all 3 reservoirs, whilst I only saw 2 Large Reds, 1 by the boardwalk around the top reservoir and 1 in the ringing area.

Large Red Damselfly

I also saw 2 species of Volucella hoverfly, Volucella pellucens and Volucella bombylans, along with 3 other species of hoverfly: Episyrphus balteatus a.k.a. Marmalade Hoverfly, Eristalis nemorum (a dronefly sp), Helophilus pendulus and Myathropa florea.

Butterflies seen were Common Blue (3 males in the ringing area), and a single Peacock (1 in the ringing area). Moths seen here were Cinnabar Moth (1) and Silver Y (1).

I was down again on Saturday (16th). The weather wasn't so good, so the number of insects was smaller. New species included Red and Black Froghopper, Straw Dot (moth), Yellow Shell (moth) and Black Snipefly.

Ringing Success

After a couple of months break, we (Sorby Breck Ringing Group) were back down at Linacre this morning for a ringing session. As the title suggests, we had a very successful morning, with 72 birds of 10 species caught and ringed. All the birds, bar two, were juvenile birds.

The most numerous species caught was Blue Tit, comprising 42 birds (38 new and 4 retraps). All birds were born this year, and the retraps were birds that had been ringed this year in the boxes throughout Linacre, which is always good to see. We also caught 4 juvenile Great Tits (3 new birds and 1 retrap that had also been ringed in a Linacre box this year), 2 Coal Tits (1 adult and 1 juvenile), 2 Long-tailed Tits (both juveniles), 1 Wren (juvenile), 1 Song Thrush (juvenile) and 1 Goldfinch (juvenile).

To supplement the resident birds, we also caught 3 species of summer migrant; Blackcap (3 juveniles), Chiffchaff (6 juveniles) and Willow Warbler (9 juveniles and 1 adult). All in all, an excellent morning's ringing.

Other bird species seen during the morning included 12 House Martins, 1 Swallow and 2 Kestrels, which could have been an adult and a juvenile. A Painted Lady butterfly was also seen, the first site record since 2013 (see here), along with 1 Peacock,  1 Red Admiral and dozens of Cinnabar Moth caterpillars.

Linacre Insects - 3rd June 2017

It was bright and sunny again today (20 degrees), so I had a couple of hours in and around the ringing site at Linacre, to see which insects were out and about. As it turned out, there were quite a few, including many "new for the year" species.

The first insect I saw was Common Blue Damselfly, which was very numerous (c.20/30 individuals), including many newly emerged individuals. A single Large Red Damselfly was also present , in exactly the same spot as last year's individual.

A single Meadow Brown butterfly (my first of 2017), was seen, as was a male Common Blue Butterfly, feeding on the Bird's Foot Trefoil, and a Large Skipper.

As well as these butterflies, there were also several day flying moths present, 3 of which I could identify: Nettle Tap Moth, Cinnabar Moth and Bloodvein.

Other species seen were: Scorpion Fly, a Mayfly sp (possibly Drake Mackerel) and a Hairy Shieldbug. All in all, an excellent couple of hours!!

Linacre WeBS - Birds, Butterflies, Damsels and Dragons

This weekend was the time to carry out this month's WeBS count at Linacre, so I was down there at 7am with Luke. We recorded  the usual species, including a good number of youngsters. Numbers were as follows: Mallard (68, including 1 brood of 5 ducklings), Tufted Duck (26, including 1 brood of 5), Mandarin Duck (19, including 8 ducklings), Moorhen (2, 1 adult and 1 juvenile), Coot (9, 5 adults and 2 broods of 3 and 2 chicks), Grey Heron (3), Grey Wagtail (5) and Great-crested Grebe (6, 2 adults and 4 juveniles). Unfortunately, no sign of the Shag, which was last reported on 19th July, but I'm sure someone will find it again soon.

The weather for this morning's walk was super, being warm (16 degrees) and sunny on arrival, and rising to 20 degrees by the time we left. As a result, there was a great deal of insect activity around the site with 4 species of butterfly, 4 species of moth seen along with several bumblebees, 2 species of damselfly and 1 species of dragonfly. The butterflies were: Small Tortoiseshell (2), Large White (3), Meadow Brown (20+) and Small Skipper (1).
