What do you use to find that out Roger?
Re: your subsequent post, despite being near-absent for much of summer, the wasps have appeared in force this last week.
You mention plums- our plum gtree has zero fruits for the first time ever, and all of the local damson, mirabelle and cherry plums are fruitless too, in contrast to the apples.
I wonder if wasps somehow manage to subconsciously respond to the conditions that cause this (or just remain latent until they smell plum!)

Best starting point is your local bat group. Go to a Bat Watch and see what they get up to.

Re the relationship between fruit/food availability and insect numbers: I will offer you a possible suggestion to research. Larval wasps are carnivorous and are fed on insects/larvae by the workers. Adult worker wasps on the other hand are attracted to carbohydrates - like nectar, honeydew, stolen honey and that jam pot or can of coke - and of course ripe and rotting fruit. At the end of a summer, a good insect year [food for larvae] will also have a good adult wasp population. A bad insect year is often also a bad fruit year due to poor pollination and/or bad weather. There will therefore be fewer adult wasps chasing after less fruit. So there is a relationship, but it is functional and real, a consequence rather than intuition.  Make sense? Here's some general stuff on Wasps:

They no longer have larvae to feed, they soon will die, meanwhile they want to eat. The significant question is how many queens have been produced, getting ready to hibernate. That will have an effect on next year's start-up population.

I note from Wiki that both Vespula vulgaris (common wasp) and V. germanica (german or paper wasp, from its habit of building paper nests) are both frequently found in the UK, but that V. vulgaris workers measure up to 17mm long whereas V. germanica workers are typically 13mm long. Am I reading too much into a chance observation by thinking that  V. germanica is more common this year?


Queens btw are typically 20mm long.

Small wasps are most likely to be female workers and there are many of these seen most years, especially end of summer into autumn. Big wasps are most likely to be queens, fewer, and for me they are especially few and far between this year. If you want a measurement you may have to catch one. The "faces" are helpful. V. vulgaris has a "black nose stripe", V. germanica a "black nose dot"! For help see:

It also quotes a pro as saying qu: Wasps normally only sting if they feel threatened
I remember an abdominal sting I received in 2003 could be the wasp being trapped under my T shirt but I've also received a sting on the back of my neck whilst walking to work in 1989. Do you think I might have wandered into territory or unwittingly brushed a plant etc?

I remember these events as they both caused large, week-long swellings and quite a bit of pain.

Well done, Bert - you are exactly right. Wasps can and do deliver multiple stings. Honeybees in contrast are kamikaze amazons, leaving a detached sting pumping venom into the victim. They go off to die. However, there are many bee species to which this generalisation does not apply. More information;

As usual, visiting our friends in SW France never disappoints on the wildlife front, being out in the remote countryside here we have seen and heard, in the last couple of days, the Bonelli Eagle that lives here. What a beautiful, majestic bird. You'd also be forgiven for thinking that you're participating in a spaghetti western because of its call.
We've also heard the owls, there's at least two in the area, and watched the bats flying at night, after the easy smorgasbord available, of flying insects attracted by the outside lamps. It's great here. There's also some deer living in their woodland but we've been too noisy for them to show themselves  to us just yet, but we have heard them and seen the signs that they are about. The family cat has been keeping the small rodents away from the house the last two days as well, but leaving them outside our Gite! At least she's doing her job I guess.

After watching a pair of blackbirds raise a small family in my garden, I was really annoyed to see one of the neighbour's cats playing with an  freshly-killed young blackbird a couple of days ago - it had had its entrails ripped out. The (dead) eye stared at me as I wrapped it in a binbag, luckily it was bin day and the bins were collected just an hour later.

The same cat killed an adult blackbird two years ago (the scream it made as it died remains with me), and it's nabbed one of the pigeons too - my neighbour's dog dove into a bush and pulled out the remains.

Infuriating, frankly, not only do cats leave piles of parasite-ridden poo for you to tread in, they infect between a third and a quarter of the UK population with a brain parasite (which modifies behaviour in other animals to make them less fearful of cats). They then kill the birds in my garden, something replicated across the country.

Poxy things. The sooner we follow Australia's laws and require them to be kept indoors, or in a "catio", the better. "Oh, but they need to be outside", the cat-lovers say... (or, in other words, our pets are your problem). Well, by that token, dogs would love to roam in packs and kill or injure small animals, like cats, but we don't let them. It's the price paid for domestication of an animal, they lose their wild liberty but gain comfy accommodation and veterinary care in exchange.

Just before the rain started on Thursday we still has six nest of house martins with chicks – perhaps 3 chicks in each so maybe 30 all together.

Since then it’s rained and rained, on two days almost all day. ‘How are they managing to feed their chicks? To catch insects in this lot’ I wondered.

This evening I’ve had time to do a bit of checking and watching. I couldn't see any chicks in the nests. I’ve seen no house martin or swallows all day. But at sunset…I saw three, then four all gently sailing on the breeze, quite high up (‘that’ll be the adults at least’, I thought, ‘but where are the chicks?’). I waited, several minutes passed, then a saw eight, ten, and a swallow! (I though they had gone), then more, so many I couldn’t count them (above twenty it get very difficult, it become educated guesswork). Then more swallows, maybe our three pairs, hard to tell at the speed they move. Then, they sky goes empty again.

It gets darker, more, many more, than twenty appear again (perhaps as many as 30?), swirling lower but at speed, and then the irritated noise only a hirundine wanting to go in a nest can make.

I left them to it thinking how blessed we are to have such fantastic, almost symbiotic, birds share our home and how lucky we are to care for them..and how amazing it is they’ve manages to fledge chicks in the recent weather! At the moment it is ‘fare well my friends’ soon it will be ‘farewell my friends and I hope to see you next year’ Bravo to all of them!

Yesterday I was able to go on a bird walk with some others from DWT around Kimmeridge with Pat Ward.
I learnt that there are more than just seagulls (dry humour alert) and we spotted these other species on the list link. Lots of LBJ's.
I know a few of the others but my knowledge is at basic level.

Thinking of insects - we have only seen single worker wasps and honeybees this year in a garden usually teeming with insects. A Red Admiral and 2 Small Tortoiseshells yesterday - the Torts checking our windows with a view to hibernation. A recent visit to one of our favourite limewoods was almost fungus-free'. Just a couple of "little brown nasties". The forest floor was very dry indeed. No hedgehogs on camera last night.

Bees very busy in ivy today, a noticeable buzz when standing under a tree overgrown with it.

Dates when I've recorded ivy first coming into flower in this area: 24/9/08, 9/9/09, 15/9/11, 19/9/12, 7/9/14, 20/9/15, 15/9/16, 20/9/17 , 29/8/18, not recorded 2019/2020, 3/10/22, 6/9/23, 14/9/24. Not systematic, but I normally get out for a longish country walk once a week.
