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: https://www.naturespot.org.uk/species/vapourer . 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:

There is a photo of three potential variations here, and an album of photos here. I’m informed the narrow-leaved type is widespread in the area, but not mentioned in the books I have.



Some Fairly Useless Signs …

Miscellaneous Posted on Mon, August 24, 2020 10:59AM

Maybe there’s a “most useless sign” competition this could be entered into. In recent years many of these “Community Links” signs have appeared in town, but I wonder why. Perhaps it’s a requirement of a funding body. Whatever the reason it seems a waste of money, environmental resources, and space. If the signs gave some idea of where you were or where they were pointing to it would be useful, they don’t. They merely point in the direction of where a road and/or path goes; we can see that surely. In most cases the road or path has been present for 50+ years. I wonder if there’ll be a phase 2 in which links to non-community places will be have unnecessary signs installed, payed for by …?



Can TV etc. Remote Controls Be Repaired?

Miscellaneous Posted on Mon, May 18, 2020 10:23PM

From my experience faulty remote controls for TVs etc. can often be made to work again, especially if just some buttons don’t work. Firstly, it’s worth checking that the batteries are OK, and also that the terminals and compartment connections are clean. If they are dirty or corroded cleaning with contact cleaner fluid might work. If batteries are OK it’s necessary to dismantle the remote, however there is some risk of damaging it in the process. Accepting that risk I usually check if there are any fixing screws, but on more modern remotes two halves of the case have to be prised gently apart.

In this case the inside of the keypad and the circuit board required cleaning with tissue paper, nothing abrasive of course. I also used contact cleaner spray with no ill effects, but it’s not essential. On re-assembly it worked as new, although I didn’t get the positioning of the round pad correct at first. I’ve done this several times on some remotes, but with a lot of use the contacts may wear away. Apart from saving money by buying a new one, it’s one less thing to be discarded / recycled for about 20 minutes effort.



Replacement Carburettor for Leaf Blower Stihl BG86

Tools Posted on Sun, September 01, 2019 10:36PM

The 2009 model machine needed a new carb., but the original type (ZAMA C1M-S141C) wasn’t available. A replacement carb. (ZAMA C1M-S261B, on left in photo) had an extra pipe to direct vented fumes into the air filter. This required a modification to the air filter housing, which was already marked-up with hole position. See video on Vimeo for more details. This is likely to be the case on other Stihl machines, as a result of  tighter emission control laws.

This is the modified air filter housing which accommodates the extra pipe (top left).



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 …

Pontypool Park

Conservation Posted on Fri, March 08, 2019 09:53PM

There were lots of fallen leaves in the park today, but this one stood out for marking the progress of a leaf miner. According to Wikipedia the larva responsible could be that of a moth, sawfly, fly, or beetle. Photo of leaf underside here.


I also found a stone arbour, which has been reconstructed about a mile away from its original position. It has good views to the south towards the Bristol Channel.



Hair Ice, South Wales, Jan 2019

Conservation Posted on Sun, January 06, 2019 11:00PM

I was lucky to find some “hair ice” formations in near-freezing conditions in south Wales UK on 4 & 5 Jan 2019. These looked like snow from a distance, but it hadn’t snowed, just cold nights down to about -2C.

It’s also known as “cotton candy” or “candy-floss” ice, and according to reports on the internet require certain fungi to form. Growing on dead beech tree logs in this case.
