Linacre Update - 20th May 2020

I had a walk around Linacre with my nephew, Luke, on 20th May. The weather was warm and sunny and we got some great views of some of the insects and birds, including one species last reported in 2011!!!

I'd better start with the bird not recorded since 2011 - SPOTTED FLYCATCHER. Our last sighting was back in June 2011 (see here). This year's sighting was in a different part of the woods that I don't normally visit, so it's possible it has been present in previous years and not spotted.

Insect wise it was also a good visit. The first sighting was a Wall Brown. This was very nice, as I had my first Linacre record of this butterfly last year. Next up was a Green Shieldbug, followed by a Small Copper, a Dingy Skipper (my first sighting since 2014!) and a Speckled Wood.

Wednesday's trip was also the first time in 2020 that we were able to record any damselflies, with two species seen: Large Red and Common Blue. These two species are recorded annually at Linacre, but this visit was the first time that I've actually seen Large Red Damselflies ovipositing (egg laying) on site. One pair was seen laying eggs in vegetation on the bottom reservoir. Exuviae of this species, and of Common Blue Damselfly were also found for the first time. The Large Red exuviae were in the ringing site, and the Common Blue (1) was found on the top reservoir.

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!

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.

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!
