Vapourer Moth Caterpillar

Wildlife Posted on Sun, October 04, 2020 09:37PM

Found in my garden at the end of September, a very impressive caterpillar also know as “Rusty Tussock”. Wish it was a bigger and could be trained to do some household chores, like dusting perhaps! This webpage (amongst others) has some more information: . The photos of the egg stage look very similar to those I found on a piece of plastic sheet last autumn; shown in photo below with caterpillars emerging in May 2020:

I wonder if these are Vapourer caterpillars, they look hairy enough. If so, and since they were only a few metres away from the more developed caterpillar, maybe it was part of this batch.

Another moth caterpillar with a raised “tail” is a Pale Tussock; see earlier post, and more info here.

Hogweed Variations?

Wildlife Posted on Tue, September 01, 2020 09:15PM

A small-white butterfly feeding on Hogweed flowers recently. This was the usual form of the plant, but there are others in the area (Pontypool, south Wales) which could be a narrow-leaved type or hybrid, or not hogweed at all. Sample photo below:

“normal” and narrow-leaved hogweed together

There is a photo of three potential variations here, and an album of photos here. I’m informed the narrow-leaved type, on the right in the above photo, is widespread in the area (see comment). This has the scientific name “Heracleum sphondylium ssp. sphondylium var angustifolium” I believe.

Mid May Sightings

Wildlife Posted on Sun, May 19, 2019 09:40PM

A couple of welcome recent sightings in Torfaen, south east Wales:

Firstly a Green Hairstreak butterfly, difficult to see when static amongst leaves, bilberry in this case. The only UK butterfly which is nearly all green (on underside of wings), mainly dark brown on top of wings. This one has some wear to the scales.

I was alerted by snorting noises near a garden shed which turned out to be two hedgehogs having a “stand-off”, possible arguing over hunting rights under the shed floor!

A fair sized, young Elm tree, around 35 feet (10m) tall. I was advised it was a Wych Elm species.

… and nearby male and female Brimstone butterflies, may be a courtship …

Getting Wintry

Wildlife Posted on Thu, December 14, 2017 03:55PM

I prefer to write “wintery” but that’s out of fashion it seems.
It’s mid-December and roses are still trying to flower, adding some welcome colour in the garden. Time now especially to feed wild birds, and it seems a squirrel, seen in a local garden …
Trying to discourage all but small birds, this cage within a cage works quite well (outer part is a cylindrical piece of wire mesh).

Busy Bees

Wildlife Posted on Thu, March 09, 2017 09:25PM

It was around 15C today (9 March 2017), which brought out quite a few large bumble bees onto my winter flowering heather. I haven’t identified the species yet – most were as shown in photos and the video. I’ve put this post into the “Wildlife” category, but the situation was my garden, and the food plant is not native to UK. I wonder how the bees are managing in our disappearing and fragmented countryside …

Blue Fungus (Cobalt Crust)

Wildlife Posted on Mon, December 19, 2016 03:04PM

I was impressed with this blue fungus growing on an oak post, initially thought it might be a lichen. A Gwent Wildlife Trust person suggested it could be Cobalt Crust fungus (Terana caerulea), later confirmed by the Gwent Fungus Group who recorded the apparently rare find. More photos can be seen here:

Pale Tussock Moth Caterpillar

Wildlife Posted on Wed, October 28, 2015 12:55AM

I was surprised to find this very striking moth caterpillar (Pale Tussock, Calliteara pudibunda) inside an inverted wheelbarrow in south east Wales (elevation approx 1000 feet, 300m). I only had an old style mobile phone with me, so it’s a poor image. A Google search for information and photos is here. This website has very good photos, and the adult moth is also impressive. It seems the species is “fairly common” in England and Wales, but a sighting made it into a local newspaper (South Wales Evening Post, with incorrect adult photo). When moving, black markings can be seen between the bright yellow segments, along with what looks like an erect red “tail”. I moved it to a safer place while wearing gloves, just as well because handling can cause skin problems.

Common Spangle Gall

Wildlife Posted on Sat, November 02, 2013 05:12AM

While walking in an area with oak trees I noticed lots of what looked like seeds on the ground. These resembled parsnip seeds – discs about 5mm across, raised one side and flattened on the other. These appear to be common spangle galls, which have fallen off the underside of oak leaves, and are abundant this year.
These galls are produced on oak leaves during the first phase of the life cycle of a small wasp (Neuroterus quercusbaccurum) – each containing an egg developing to a larva. I failed to see one within the plant material, guess they’re pretty small at this stage (in late October).
The second phase also produces a gall (termed a “currant gall”) on oak leaf buds in early summer, from which wasps emerge. These galls are much less abundant than spangle galls due to actions of a wide variety of predators. Here are a couple of links to the many web pages on galls –
Trees for Life – this species is under the heading “Currant Galls”
Wikipedia Neuroterus quercusbaccarum

Note: Although this is called “common”, like many things in nature it may be prolific one year in a particular area, then not so for some time.

Update 30 Aug 2017
I didn’t see much of this species again until this year (I wasn’t looking hard), but it’s noticeably another abundant year in south east Wales (sample photo).
