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 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.

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.

Hoverflies were present in good numbers with numerous Eristalsis sp seen, a single Helophilus pendulus , 1 Volucella pellucens (Great Pied Hoverfly), 1 Volucella bombylans and a couple of "as yet unknown" species!!

Great Pied Hoverfly

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