Wasps are great! Some social wasps can not only recognize individuals of their own species, they can recognize humans as well and “befriend” people!
I’ve had positive experiences with the yellowjackets that live around campus at my school- my school is full of insect lovers who are pretty chill about them, and I think they recognize that at least some of the humans around them are friendly, as they’ll often land on me or share a bite of my lunch, but have never stung me or been aggressive, and I haven’t heard anyone talk about them stinging people.
There are also lots of cool wasps outside of yellowjackets and hornets, many of which cannot sting. Some of them are ridiculously tiny- the smallest insect in the world is a type of fairy wasp smaller than some single-called parameciums and amoebas. (Wikipedia article here if you’re interested.) Wasps are incredibly diverse and beautiful, and we needn’t fear and loathe them because a few of them might sting.

I saw this posted on reddit to a wholesome memes sub, and it was full of nothing but people being unnecessarily awful on a post trying to spread information about why these creatures are beautiful and worthy of living. (Interesting note: They don't need a reason to be allowed to live.) I got sick of trying to correct people on there who were more interested in hating wasps than hearing the truth.
Honestly, it's just exhausting sometimes.

NO ANTI-WASP SENTIMENTS ON THIS POST
Wow. Just wow. I’d heard about bees playing, but I didn’t know some of the other cool things mentioned in this video, like the fact that bees can learn by watching others. 💛🐝
This is why I don’t squash insects that happen to wander into the house. This is why I am against that sort of careless killing. Because we so drastically underestimate what insects are capable of. They are living beings, quite possibly each with their own desires and fears and inner lives. Many people forget that insects are animals. Many people forget that so are we.
honestly, the things that insects are capable of will never cease to amaze me
The college I work for has recently got some hives and they kindly paid for me and my colleagues to do an amazing beekeeping course.
This week I did a solo hive inspection for the very first time, as I was the only trained person on site.
It has been a magnificent, if nerve-wracking experience and I can't wait to do it again next week. I am forever petrified of squishing the queen but I will hopefully get more confident with time.
We have one large hive and one smaller one. The large hive is going strong and each week we have to rearrange everything so they don't run out of space. To do this you move empty frames towards the centre of the brood box so the Queen has access to at least 2 empty frames. For some reason she only likes laying eggs on frames near the centre. You also have to check that there's enough space in the supers as this is where worker bee store most of the honey. If the colony doesn't have enough space then the bees start to get agitated and it can prompt a swarm.
The smaller hive unfortunately lost its Queen when it was being delivered to us. So we are currently trying to raise a new one. To do this we moved over a tester frame containing newly laid eggs and some grubs from our other hive. The worker bees then chose the new Queens and built special large cells for them. we knocked down all but one of these to stop a potential swarm. We then left this hive for 3-weeks to give her a chance to emerge and go on her nuptial flight. On this flight she will hopefully have mated with a number of genetically diverse drones. She has around a 30% chance of surviving this and coming back to the hive. We haven't seen her yet but fingers crossed she's there. The workers had started to make play cups indicating that they are dissatisfied with the lack of new eggs being laid. But it does take a while for her to start laying. As we don't know if she survived I put in two new tester frames with eggs and grubs from the other hive. When I do an inspection next week I will need to check for freshly laid eggs and queen cells. If I see new eggs then I know that the Queen survived, but if not and if Queen cells have been produced then we'll have to start the process of raising a Queen again.
The pictures above are from the smaller hive showing some play cups on a couple of the frames. This shows the workers are irritated at the lack of new eggs being laid. One picture also shows the entrance to the hive and one of the worker bees has pollen on their legs. This is apparently an indication that a new queen is present and is about to start laying.
General Bee info:
The Queen has a store of sperm and can control which eggs are fertilised with a little flap. Unfertilized eggs turn into drones (haploid, reproductive males). Fertile eggs turn into either worker bees (usually non reproductive, female bees) or new Queens. She lays individual eggs into each of the cells.
In a healthy hive, drones are only present in the summertime when the hive has reached sexual maturity. In an unhealthy hive the Queen can start laying drone eggs when she runs out of stored sperm. Queenless workers may also start to lay drone eggs.
When the eggs hatch, worker bees feed and nurture the grubbs with honey and variety of different pollen. It is the worker bees that choose what fertile eggs become Queens. The ones they select as potential new Queens are fed a diet of mostly royal jelly and they build larger cells for them. Workers can also choose when new queen's emerge by standing on top of the flap door to their cell. This prevents them from emerging until the workers deem the time is right.
As time progresses grubs get larger and eventually pupate within their cells. The cells are then capped with wax and the pupae starts to metamorphose internally. When the pupa are fully developed they moult and then chew their way through the wax cap. Young bees can be quite light-colored when they first emerge.
Unfortunately I don't have very many pictures of our lovely hives. It is quite hard to take photos with massive gloves on, and the longer you spend faffing around, the more stressed out the bees get. I only got these pictures because I needed to update my colleagues on certain developments. If the opportunity arises again then I will share any photos here as I think bees are really interesting.
Gatekeeper ant! Found her in a pool, she's absolutely beautiful
Okay, so this is really cool! You have this phenomenon where some plants grow edible appendages to their seeds to entice ants to carry them underground where they can safely sprout. And then you have wasps which lay their eggs on the leaves, stems, and other parts of plants and trigger the growth of galls (swellings) which both feed and protect the wasp larvae until they reach maturity.
The boy who was watching the ants noticed they were taking wasp galls underground, too. Further exploration found that the wasp larvae were unharmed inside the galls; the only thing the ants had eaten were edible appendages similar to those on the seeds they collected. The wasp larvae stayed safe inside the ant nest, feeding on their galls, until it was time to emerge and head back out to the surface.
So it turns out that the edible portions of the galls have the same sorts of fatty acids as the edible parts of the seeds. And those fatty acids are also found in dead insects. Scientists think that the wasps evolved a way to make the galls they created mimic the edible portions of the seeds to get the ants to collect the galls. This isn't the only example of wasps making use of ants as caretakers for their young, but it's a really fascinating example thereof--especially if you consider ants evolved from wasps at least 100 million years ago.
I’m the world’s worse advocate for wasps. Everytime I see people repeating bees=nice good pollinators wasps=bad stinging meanies, I face a deep internal struggle trying to explain how they are important to the environment without explaining wasp facts that freak them out in ways they never even thought
If wasps have 5,000,000 fans, I am one of them If wasps have only a 100 fans, I am still one of them If wasps have only 1 fan left, that is me If wasps have no more fans it is because I am no longer in this world my mother gave me my life, but wasps gave me a reason to live it
