More from Murlough

Bioblitz at Murlough:

I had set people the task of bringing back any leaf galls that they found, and my workbench was soon loaded down with specimens.

The first specimen brought in was Aceria pseudoplatani made by a gall mite on Sycamore:

The gall is on the underside of the leaf, but is visible from the top as a yellow depression which makes it quite obvious. There is one previous record from Dublin last year. Murlough is also on the east coast, so I suspect it might just be newly colonising from the UK.

This Phanacis hypochoeridis (wasp) gall on Catsear was locally very common: I saw it in a couple of separate locations and almost every plant seemed to be galled. It's described as rare, so it must be very local. First Irish record was submitted last week after I identified the specimen! Each gall is a series of chambers, each one containing a yellow larva.

New to my Species List
Bombus lapidarius - Red-tailed Bumblebee isn't rare, but I have never seen it on my patch. Here it is gathering pollen on a new flower for me: Restharrow

Both new to my Species list

This Yellow Shell moth flew over my shoulder and hid under a stile step. So this shot is taken with me lying on my back facing upwards at the underside of the step. Flash used.

New to my Species List (which is badly in need of an update now!)

I'm getting lots of reports of the excellent hoverfly Volucella pellucens at the moment:

This was also taken at Murlough:

This Cixiid landed on my recording sheet and I managed to get a couple of shots rattled off before it flew. It isn't the much more common Cixius nervosus, and seems to match Cixius cunicularius very closely.

I can't find any previous records for this local species in Ireland.

I think my personal species tally for Murlogh was around 200, with 2-3 new records for NI and perhaps one new species for Ireland. I'm awaiting confirmation of id's before I report fully.
