The stings also embed themselves into your skins and sort of saw their way into you with barbs. Bad news. Mostly you can hear when a hive is about to get mad, they'll go from a low hum to a slightly louder higher pitched hum when they're getting angry. Bees make a lot more sense once you start treating a colony as an entity and not the individual bees.

I think it's a truck like this  that has been hot-rodded to have a front end similar to this: edit: Similar to this maybe:  I don't know how many cars came with split windows, but they aren't totally uncommon on older trucks. But long story short I'd wager it's definitely a split window hot rod. AFewBricksShy fucked around with this message at 14:46 on Jun 22, 2020 |

Aramoro posted:Yeah this is something you learn about when you take up beekeeping. Step 1 is requeening the hive and see if that fixes it but if not you just have to destroy the hive. Normally you have to wear the bee suit to prevent accidental strings but when they're flying at your face and bouncing off the mask then it's really hard to work. There will be 50,000-60,000 bees in a hive and once they drop the alarm signal and start stinging more and more bees will come at you. Since they can only sting once doesn't that kind of destroy the hive any way? Once the worker population's gone full kamikaze on you what's left to feed the brood?

Not really, a bad bee attack they might sting you what 500 times and you're probably having a bad time. The queen can lay 1000-1500 new bees every day. After the bees hatch for the first couple of weeks they'll exclusively stay in the hive, cleaning, feeding, drying honey etc these are called House Bees. After that they'll start flying outside to forage and then older again bees are the ones can can make wax for building. So out of a hive of 60,000 bees about 1/3rd or 20,000 will be foraging for water, nectar and propolis with a portion of the foragers guarding the hive. Active guards you've probably got a few dozen depending on the threats that have been around but once those guards have been alerted other foragers will join in. So of that 20,000 bees you'll probably only get attacked by maybe a couple of thousand as the other will be out foraging and no where near. All they're trying to do is drive you off so once you start to leave they;ll stop attacking you. For me if the hive is upset at an inspection going 6ft away is enough to stop them attacking. Bees can only really string mammals once, the modified ovipositor used for stinging developed to work its way through thick mammal skin with alternating barbs which is why it kills the bee to do it. I think this applies to all honeybees, not just western ones. Asian honeybees do have a lot of differences but not sure that's one. Aramoro fucked around with this message at 16:41 on Jun 22, 2020 |

Moo the cow posted:This is not a particularly reassuring statement. Oh no it's definitely super bad for you. But for normal honey bees (Apis Mellifera here) if I went and stood 6ft from the hive no issues. if I stood a foot from the hive might attract some interest. If I put my finger into the entrance I'd get a couple of stings and more guards would come out to see what the gently caress. If I didn't move away it would escalate. If I opened the hive and started to mess with it all bets are off and it's a bad time. The attacks start small and snowball. The problem with those bees is they go straight to 100 for even being close to the hive. Way way too aggressive. Its why you need extensive public liability insurance and training for keeping beehives on public land. Not because they're particularly dangerous but people will go and gently caress with them, hitting them, kicking them over trying to open them up and that usually involves a trip to hospital unless it's a very cold day.

Moo the cow posted:Your posts are genuinely fascinating. Nothing like that. The aggression goes up and down through the year, as they have more stores in the hive they tend to be more aggressive as they have something to defend. A swarm is the opposite end of that, they have nothing to defend so just don't attack people. I've had what we would call an aggressive hive and at it's worst when I've bumped the hive or set a frame down into it too hard I've had a bunch of bees flying up into my face but manageable. Until that time they got into my suit and stung me on the temple, which sucked a lot. If you move slowly and calmly usually you wont upset them too much. Smoke can help as they run away from it to eat as much honey as they can because they think they're about to evacuate. That does kinda stress the hive though so I tend not to use much smoke. If you follow the guidelines it's pretty safe generally.

So the thousands of bees attacking that guy nonstop are for the most part, not stinging? I figured that if one's landing on the guy it's there to sting. I also guess that maybe the barbs don't catch in beekeeper suits. Don't they secrete a pheromone that says "Come here and sting this guy?

I also guess that maybe the barbs don't catch in beekeeper suits. A lot of them are trying to but failing, they're looking for where to sting, usually around the eyes which is why they're flying at his face, some will try to go up the inside of the trouser legs, into sleeves etc. They'll usually not sting unless they're going to hit flesh. They are sending out pheromones to attack but not all will be able to sting you for various reasons. Normally someone would run away and they'd stop. That video is an especially bad example, that's way way more extreme than you're ever likely to see. They've started stinging so it's just snowballing like you see there.

If you want an OSHA-laden show to watch, try Canada's Worst Handyman. It's a show where they take people who are extremely bad at DIY and home repairs (either because they're scared to learn how to be self-sufficient or they think they're amazing but are actually incompetent and dangerous) and have them try to complete basic home renovation and repair challenges as you marvel at how bad they are. https://www.youtube.com/watch?v=Zn6B5csEH3I

Yeah CWH is delightful, in that they are always provided with very clear instructions and often a lesson beforehand, and are usually still hopeless. Worst Driver is decent too, though lots of countries have their own flavor of those.

I know in reef aquaria, LED lighting has all but completely replaced metal halide lighting, even for extreme intensity applications. From my experience with concert and stage lighting, it's happening, but there's still a lot of hold outs. Every year I've been seeing more and more LEDs replacing old style light roles, along with some novel LED lights in new roles. Stage lights aren't cheap, so existing lights aren't getting switched out unless there's a good reason. We're gonna be seeing the army of existing source 4s around in the theater forever, while some concerts are completely LED + moving light based. I haven't seen any LED based 4ks or followspots, that role of loving huge bright light is still exclusive to legacy systems in my experience. From my very limited movie experience, they're still ruled by older tech. It's so much nicer to run power for LED systems. Lighter and fewer cables is easier on my back and arms.

The Dutch version of Worst Driver actually had what I think is the only serious injury! https://www.youtube.com/watch?v=nvckBJP8QPU This is a shoulder check challenge. You drive toward a wall and turn around to look at the signs indicating which way to go around the wall. When confronted by choice, he instead closes his eyes, slams on the gas (mistaking it for the brake), and turns the wheel to the right as hard as possible until he runs over the host and a cameraman and crashes into a staff car! These shows are amazing but also terrifying for showing you just how many drivers are out there who are insanely dangerous at the wheel despite getting a license. Ever wonder why you'll be driving down the highway and encounter someone who somehow had a rollover crash on a straightaway on a sunny day without traffic? Because there are people who, when something mildly unexpected happens, react like this.
