Miscellaneous Delights

/ nrowberry / Leave a comment

Despite being stuck at home like many people, for much of this year, I don’t seem to have blogged as much as I would have liked. It certainly wasn’t for lack of interest in the garden – having spent an inordinate amount of time sitting out, there was plenty to see. Perhaps there was too much, or perhaps I just couldn’t face being cooped up inside to write. Whatever the reason, I’ve ended up with a lot of interesting (to me at least) snippets, that never saw the light of day. So here’s a miscellany of wildlife moments from the garden this year – they all cheered me up and they deserve their moment!

Most of this will be insects, but there are a trio of mammals making the cut.  Hedgehogs of course featured regularly in the garden. Freda our 3-legged hedgehog from the previous year not only made it through the winter, but produced at least one hoglet. Here she is looking like many mums – slightly harassed by her offspring.

 

Bats (most likely Common Pipistrelles) have always used our garden as a hunting ground in the summer months. A weed-filled garden tends also to be an insect-filled garden, so there are plenty of moths and other food for them. It may be wishful thinking on my part, but the bats do seem to be coming more frequently now we have the new pond. The pond is surely generating extra insect activity, which hopefully means more bats. I’ve tried with very limited success to film them – this was the best of a shoddy selection of shaky videos. I reckon there are at least 3 bats visible towards the end of the clip.

Third mammal is this mouse at the bird feeder, for no other reason than it was so cute.

So on to the insects. I was really chuffed to spot a Dotted Bee-fly again this year, amongst all the regular bee-flies. Both species seemed to favour warm stones around the pond.

 

 

 

 

 

 

Hoverflies were abundant in the garden and as usual I failed completely to get to grips with identifying them all. There were lots of different shapes and colours though, including some of the delightful bee mimic ones.

 

 

 

 

 

 

 

 

 

 

One I did manage to identify though was the Hornet Mimic Hoverfly (Volucella zonaria) – one of the biggest British species. They really were huge compared to the other hoverflies.

A new species to me and in fact a new group was this Potter Wasp – so called because some species construct little mud pots for nests.

Continuing on the waspy theme, here’s one of the gorgeous ruby-tailed wasp species. I tend to have mixed feelings towards these – they are of course stunningly beautiful, but they do parasitize mason bee nests and I feel very protective of my little mason bees. But live and let live and it’s nice to have diversity in the garden.

The wasps aren’t the only parasitic insects in the garden. I discovered this new addition to our garden bee fauna this year – a Sharp-tailed bee Coelioxys sp.  These ones make use of leaf-cutter bee nests.

Talking of leafcutter bees, I had meant to do a whole blog post on them. I’ve got a lot of photos and a lot of videos – so many in fact I think it became too daunting to sort through. So a full leafcutter post will have to wait until next year. In the meantime here’s a snippet.

 

We’ve had a few interesting beetles this year too. This one I spotted on the garage wall, while out checking the moth trap one night. For a split second I thought I’d got a Stag Beetle, then reality set in and I realised it was a Lesser Stag Beetle. Still a first for the garden, so very pleased to add it to our list.

The pond of course attracted lots of water beetles. This huge Great Diving Beetle misjudged his landing though and ended up in the hedgehog’s water bowl.

Also misjudging his landing was this Dung Beetle (Onthophagus coenobita) which ended up on a bit of frogbit in the pond.

Moths I’ve covered fairly extensively in other blog posts, but possibly my favourite odd moment this year was watching a male Black Arches moth flare it’s genitalia at me! It was perched on the edge of a pot and while I tried to photograph it, it started this weird behaviour. Don’t know whether it was trying to warn me off, or perhaps entice me (should I be flattered?), but it was certainly very odd. I sent the video clip to some moth experts and they weren’t sure why it was doing it either.

So that’s it really – a quick round-up of some of the wonderful wildlife I was lucky enough to see in our garden, but didn’t manage to blog about before. I feel very lucky to have had a garden to enjoy in 2020; it really has made things a lot easier to deal with when you’re surrounded by so much wildlife.

I’ll do a summary of everything else we’ve seen this year in the next blog post, with hopes and dreams for next year too. Happy New Year everyone. xx

 

 

 

Slugs Count

/ nrowberry / 6 Comments

Way back at the beginning of the year (when the world seemed a very different place) I saw an article asking for volunteers to count slugs. The RHS in conjunction with Newcastle University were looking for 60 people to go out into their gardens once a month and count & identify the slugs in their own gardens. Perhaps I need to get out more, but it sounded great! Since I already spend a lot of time looking at the moths, bees, dragonflies etc. in the garden, it seemed a good opportunity to learn a bit about another group. So I applied and then lockdown happened and everything went on hold.

But eventually I heard back; they’d had nearly 3000 applicants for the 60 volunteers needed, so I feel really lucky to have been chosen. Our survey packs arrived, complete with sampling containers, slug guide and pre-paid postage envelopes (the local post office are going to love me). In an ideal world we would have all met up for hands-on training, but thanks of course to COVID, we had to do all this by Zoom.

First thing I learned about identifying slugs is that it’s really hard! They are extremely variable and they either keep moving or they scrunch themselves up so that you can’t see the bits you need to see. They’re also really hard to take photos of, because again they either keep moving or they’re shiny with slime so that the camera struggles to focus.

Splitting them into the major groups seems relatively straightforward until you get very small ones.  If the breathing pore is in the front half of the mantle (the fleshy sort of saddle on their backs) then it’s one of the Arion types like the one below.

If the breathing pore is in the rear half then it’s one of the keeled slugs like the one below. So far so good.

But separating the keeled slugs is also tricky. There are long keeled slugs and 2 groups of short keeled slugs and the keels really aren’t always that obvious.

Originally it was all planned to start in June but in the end it was early November before we all did our first slug counts! A half hour search around the garden after dark yielded 116 slugs! And that’s without lifting anything up, or rummaging through leaves or plants – just scanning around with my head torch (neighbours once again convinced I’d lost it). So here they are before I’d sorted them out – a bucket of slugs.

And then all potted up with their moist capillary matting to stop them drying out and shredded carrot for the journey.

The lovely post office lady did indeed thing I was a bit odd to say the least when she asked what was in the parcels. I have since done my second count in early December; a mere 88 slugs this time. Many of the other slug count participants have been reporting only a few or even no slugs at all, but that’s clearly not an issue in our garden. I suspect it may be because our garden is so unkempt with plenty of decaying matter for them to feed on – slug paradise.

By far the commonest species so far has been Arion (Kobeltia) hortensis – the Blue-black soil slug. They’re only 2 -3 cm long, but what they lack in size they make up for in numbers; the garden is full of them.

There were also apparently some other small Kobeltia species in my samples, but I’m waiting confirmation of what those are. A few juvenile Arion subfuscus had also sneaked in undetected (by me). Differentiating between some of these is way beyond my current skills set.

The next most common species was Deroceras reticulatum, the Netted Field Slug. This is one of the slugs with a short keel. I found these short keeled slugs really hard to photograph and show the keel, so you may just have to take my word for it that there is one there.

Apparently in my samples there were also some Ambigolimax sp., but since I failed to spot these as being anything different, I don’t have any photos.

I did better with 2 species of long-keeled slugs – Tandonia budapestensis – the Budapest Keeled Slug and Tandonia cristata  – the Crimean Keeled Slug. I managed some photos of the Budapest ones (below) but seem to have got so excited when I spotted the second species that I forgot to take any photos. The keel on the Budapest ones is really nice and obvious – my kind of slug!

The only other species to get picked up in my half hour searches was a single Limacus maculatus – the Green Cellar Slug, although this specimen doesn’t look especially green.

The cellar slug above was by far the biggest slug I collected during the counts so far, but I know we have much bigger slugs in the garden like this giant Arion seen last summer.

The weather is now significantly colder (first snow today) but there are still a fair few slugs out at night. Hopefully in the coming monthly surveys I will find more species new to the garden. I’m finding the whole process fascinating and it’s opened up a whole new world of wildlife to me. Hopefully the slugs in our garden and in those of the other slug count participants will help the scientists to expand their knowledge of this understudied group.
