*Warning*: as you may have guessed, this post contains spiders. Some people may find some of these photos unpleasant, but it may help you to learn to overcome your fear. I am not a spider-psychologist so this is not professional advice, as ever.

Here are frequently asked questions about spiders if you want to dispel any myths!

Well, what a week that was. Very high nightime temperatures and unbearable heat through the day. I barely spent any time outdoors, let alone in the garden. I really struggle in temperatures over 30 degrees. Most of the images this week come from the post-heatwave days towards the end of the week.

One evening, after the heat had largely dipped, I noticed some odd behaviour from a zebra jumping spider.

GDN_16-8-2020_lo-res-23

It was hanging from the leaf of a climbing rose we have growing from a terracotta pot on the front of our house.

I noticed there was another, smaller, zebra jumping spider (ZJS) lower down on the pot. I think this was some kind of territorial or even courting behaviour. Eventually the ZJS made it down to the terracotta.

It was running around on the edge of the pot, looking for the smaller ZJS. It was a total nightmare to get in focus.

There was also some time to clean its legs while it tried to find out what the other ZJS was up to.

I’ve seen these lovely spiders all throughout the spring, but much less so in the summer. It was nice to see them again.

I also noticed this crab spider floating in midair on its silk. There is something quite weird about this image I think. The limbs look a bit like human or robot arms. This was a pure fluke of hoping it got into focus, even then you can’t really see the spider properly.

I’ve noticed far fewer insects in my garden, probably because the plants we have are largely over. I need to get some late-summer to autumn flowering species like stonecrop to keep things rocking and rolling. I had a look through the hedge while having an afternoon break after the storm took the heat away. I noticed this spider tucked away down in a bunch of leaves in the hedge. The silk is there to help catch prey but also it will react to movement, triggering the spider to attack.

I visited my family home for the first time in 6 months last weekend, a really special experience after such a long time away. My parents are avid readers of this (perhaps that should say, the readers) blog and my mum pointed out to me that there was a big spider in the bath that I might want to include here! YES MUM!

Now there have been several times this week when I’ve noticed out of the corner of my eye a shadow moving across the floor. This is something a lot of people are very unhappy about! But it’s the time of year when giant house spiders are becoming more evident. They are fiersome looking things yet they are harmless. They are more afraid of you than you are of it. They have every right to be afraid, because people will likely try and kill them when they see them, out of misplaced fear.

OLYMPUS DIGITAL CAMERA

That said, they are a bit scary to look at and those mandibles are massive. I had my small mirrorless camera with me and a macro lens. The images are quite harsh and grainy because the light was so dank and the flash is a pop-up one without a diffuser.

OLYMPUS DIGITAL CAMERA

The spider didn’t actually mind me at all. It was trying to remove some spider silk from its legs by running them through its mandibles.

Far from wanting to harm this animal, I am pleased that we can have such close encounters with big insects like these. If you let them go about their business, there’s no problem. No spider in Britain is venomous. This is not Australia!

Thanks for reading.

Macro Monday 25th May 2020

Happy Bank Holiday Monday to British readers. Recent weather has been hot, with strong winds coming in on Friday, blowing macro out of the equation. I’ve kept to my routine of garden and local walking.

Last week I said the bumblebee workers were beginning to appear, and this week I’m keeping up to my promise.

I took lots of photos of bumblebees visiting flowers but they are very difficult to get in focus because of the shallow depth of field that macro lenses have. Therefore, the only decent photos I got were the header image and this here. These open spiked flowers are excellent for bumblebees, similar to foxgloves.

I had better luck with the solitary bees such as this mason bee visiting a cranesbill flower. I’ve noticed that our bee hotel is now quiet and the early spring activity has ended. But the mason bees are still active. I wonder where they’re spending their time?

OLYMPUS DIGITAL CAMERA

A few weeks ago I mentioned a mason bee that was giving me the right royal runaround. I think this is the same bee. I can see it from the window upstairs as it find the same place to bask on a sleeper that separates our garden from the brick patio.

Here he or she is again up close. I love the golden sheen of its head, it’s almost like something from an episode of Ru Paul’s Drag Race.

This is a new bee for my garden list and a species I haven’t seen before. It’s a relative of the hairy-footed flower bee which is a common early spring species. I think it’s a four-banded flower bee, Anthophora quadrimaculata. They nest in buildings. There’s plenty of dodgy mortar around where I live to provide them with a home.

Moving on from the bees, despite what this hoverfly may have wanted, many species pretend to have the look of a wasp or bee. This is an area of evolutionary biology I’d like to learn more about (if you know a good book, please let me know). This is a bee-mimicking hoverfly. This one is mimicking a carder bumblebee with its ginger thorax (I’ve got one too).

OLYMPUS DIGITAL CAMERA

It’s not just hoverflies that mimic bees and wasps. One afternoon I noticed there was a wasp beetle sitting on my window ledge. In London I’ve seen these beetles on yellow and black things that help them to camouflage. I once saw one on the pedestrian road crossing box which is black and yellow. Urban insectlife at its best.

In the bug world I found this mirid bug posing on the lamb’s ear (which, by the way, is so close to flowering). It had a lovely orange glow to its body and eye, merging with the green.

When I was a teenager I can recall insects crash landing behind the TV on summer nights when we had the window open. The culprit was almost always a hawthorn shieldbug smashing into the lamp. This week one tried to join me at my desk while I worked from home. Perhaps this was the same bug that I originally met on the garden fence.

Having spent time trying to find jumping spiders, they are now coming to me. Eating lunch in the garden, I have found jumping spiders exploring my arms and legs. They’re really very sweet arachnids. I’m not sure if it’s producing this spider silk or just crossing it.

OLYMPUS DIGITAL CAMERA

This was another chance encounter in the lamb’s ear, where all the cool invertebrates hang out. I couldn’t resist keeping the background bokeh in the crop.

OLYMPUS DIGITAL CAMERA

I accept that some spiders are less cute and fluffy. But this yellow crab spider was incredible. It was hanging around the lamb’s ear seeking its prey. It didn’t really mind me getting close with my small mirrorless camera. I know many people are missing hugs right now, but this probably isn’t the hug you’re looking for.

Thanks for reading.
