Linacre Insects - A New Species!

 I was down at Linacre on Thursday (29th) doing the last check on the nestboxes (more details to follow). The weather was pretty decent, with sunny spells and temperatures in the high teens, so I managed to spot a few insects too, including a new species for Linacre - Burnet Companion. 

Burnet Companion is a species of day-flying moth. It's pretty common, but hasn't been recorded here before, so this sighting was a very nice one.

Other species seen were: Common Blue Damselfly (3 males), Wall Brown ( 1 worn male), 1 Scorpion Fly, Nettletap (moth), Swollen-thighed Beetle, Large White (1) and a couple of hoverflies; Helophilus pendulus and Myathropa florea.

Linacre - 31st August 2024

 Based on the year so far, this afternoon's walk around Linacre, was by far the best one for insects this summer. In total, I saw 7 different species of butterfly, along with 3 dragonfly species, 4 hoverfly species and a few other insects. In addition, I go my first Linacre Hobby since 2013!!

The butterflies seen were: Peacock (9), Red Admiral (5), Speckled Wood (5), Large White (1), Small White (4), Comma (2) and Meadow Brown (2).

The dragonfly species were: Migrant Hawker (2), Brown Hawker (2) and Common Darter (1).

The hoverfly species were: Eristalis sp, Helophilus pendulus (1), Volucella pellucens a.k.a Great Pied Hoverfly and (1)Volucella inanis (1). Other insects seen included a Scorpion Fly, a 7-spot Ladybird and a Large Yellow Underwing.

Birdwise, it was quite quiet, but the obvious highlight was a Hobby that was chasing a couple of Swallows! My last Linacre record of this species was way back in September 2013!! Other birds seen were: Canada Goose (20 on the top reservoir), Great-crested Grebe (4; 2 adults and 2 juveniles), Little Grebe (1), Swallow ( 4 in total), wheeting Chiffchaffs, Grey Heron (1), Tufted Duck,  Mallard and Mandarin Duck.

Linacre Update - 11th May 2024

 Yesterday morning I went down to Linacre to carry out this month's WeBS count, and to catch up with the nestboxes.

The WeBS count was, as usual for May, quite quiet, with the following birds recorded: Mallard (46 birds; 32 adults and 14 ducklings - 4 broods of 5, 5, 3 and 1), Tufted Duck (4!), Grey Wagtail (2; 1 male and 1 female), Grey Heron (1), Coot (5 adults), Moorhen (4 adults) and Mandarin Duck (10).

The nestboxes, on the other hand, were much more exciting! I found our first full clutches Pied Flycatcher eggs of the year (2 nests, each containing 5 eggs). Another 2 singing males were also heard away from these boxes, so I'm keeping everything crossed for further nests. The Coal Tit and Wren nests were still going strong, and the first Blue Tit chicks of the year had hatched. In total, we now have 43 active nests on site - a very good year! Other birds recorded around the site were 3 Blackcap, 4 Chiffchaffs and 1 singing Garden Warbler.

On Thursday, I was also on site, with Chloe, to ring the adult Mandarin Duck that is nesting on site. This year, we also added a colour ring, so hopefully, we'll get some more sightings of her.

Last, but by no means least, I also managed to spot a few insects: 2 female Orange Tips, 1 Green-veined White, 1 Helophilus pendulus, 1 Common Carder Bumblebee, 1 Red-tailed Bumblebee and 1 Hairy Shieldbug.

Linacre Insects - 4th September 2022

 It was 21 degrees on Sunday, so I had a couple of hours around Linacre to see which insects were still flying.

It started well, with a Red Admiral, followed by 3 Speckled Woods, 1 Large White and 1 Small Copper, of the form caeruleo-punctata (blue spots of the wings).

Small Copper

Dragonflies were far and few between, but 3 Brown Hawkers were seen, including 1 that posed nicely by the bottom reservoir.

There were a few hoverflies, mainly Eristalis species, but I did manage to spot one Helophilus pendulus and  this one, which I believe is a Sericomyia silentis (my first record since 2017).

Sericomyia silentis

Birds seen on site included: Tawny Owl (1 in the ringing site), Buzzard (1), Grey Wagtail (4, including at least one juvenile), Great-crested Grebe (2 adults and one juvenile), 1 Chiffchaff (still singing in the sun) and this juvenile Tufted Duck.

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.

Liancre - Two new Insects

Last week whilst walking around Linacre in the sunshine, I took some photos of a couple of insects that I couldn't identify at the time. I put them on Twitter, and managed to get a positive i.d. for one species, and the family name for another.

The first species, was a type of Solitary Bee called Nomada goodeniana. This bee is a kleptoparasitic species that lays its eggs in the nest of other bees, mainly Andrena (Mining Bees) species. Interestingly, I've never recorded any Andrena bees at Linacre, so they're probably out there somewhere too! Its flight period is usually up to June, so this record is quite late. Anyway, here are a couple of pictures.

The second species was a type of Sawfly (Tenthredo spp). Unfortunately, we weren't able to identify it to species level. Here are a couple of photos if anyone knows the species.

Tenthredo spp

Along with these 2 species, I also had my first record of Helophilus pendulus on the 23rd August. This is a common hoverfly species at Linacre, but, for some reason, its the first one I've seen this year.

Shieldbugs, Flies, Grasshoppers and Hoverflies

Whilst ringing at Linacre yesterday the sun came out and I spent some time searching out some of the insects with Luke, my nephew. Together we found 3 shieldbug species, 3 hoverfly species, a new fly species and a couple of Field Grasshoppers. The shieldbugs were new records for me at Linacre, as was the grasshopper and one of the hoverflies. Lovely!!!

The Field Grasshopper is a common, widespread species throughout Britain (see here for details), but this is the first time I've managed to see and identify one at Linacre.

 We also spotted this beauty, a Noon Fly (Mesembrina meridiana) Again, this is a common species, but my first record. More details here.

 The shieldbugs were all new to me at Linacre. Here's the first one, the Common Green Shieldbug. The top photo shows the adult, and the bottom photo shows a "fourth instar" nymph. Apparently, young shieldbugs moult several times before they become adults and each time they moult, they look different. See here for pictures of the different moults.

Another species we saw was the Bronze Shieldbug. This time I'm sure this individual is a "final instar nymph". See here for more images.

The final shieldbug was a Hairy Shieldbug, another common and widespread species, but my first at Linacre. See here for more details.

The hoverflies were a Drone Fly species (Eristalsis pertinax), a Helophilus species, most likely Helophilus pendulus and a Syrphus species. The Syrphus species is particularly tricky to identify as there are 3 very similar species that can only be separated under good magnification. Unfortunately I didn't have a hand lens with me and the hoverfly wouldn't sit still!

Return to Chatsworth

The sun was shining again yesterday, so, after a morning ringing session in Sheffield, where we caught 18 birds including a Chiffchaff and a Blackcap, I went out to Chatsworth House for another look around the sculptures again, this time with my son and his girlfriend, father in law, wife and daughter!

Whilst there, I was drawn to the flowers where I managed to spot a few butterflies (Comma x 1, Small Tortoiseshell x 3, Speckled Wood x1, Small White x 1, Small Copper x 1 and Silver Y moth x 3) and 5 species of hoverfly. Here are a few photos:

I think the hoverflies are all correctly identified. The last one, Eupeodus luniger, is a "lifer" for me!
