This is (fortunately) why there's a maximum size on insects. The environment is less oxygen rich today than in the eras of giant insects in the past. They reach a size where oxygen can't penetrate deeply enough onto their bodies.

don't beekeepers use smoke or some such?

[–] Leeks@lemmy.world 33 points 1 month ago (3 children)

Yup. It simulates a forest fire and encourages them to gorge themselves on honey and leave the hive. They get less protective of the hive (because they think it is doomed) which makes it easier to work. They will check back in under an hour to see if the hive made it, and if so, will regurgitate the honey back and continue on with their day.

This sounds strange. You really don't want to make them abandon the hive. You want to disrupt the hive as little as possible.

[–] Leeks@lemmy.world 8 points 1 month ago* (last edited 1 month ago) (3 children)

My main goal is to not get stung! Also you only go into the hives every few weeks so it’s not a major disruption. Also they only temporarily abandon the hive. They check on it later to see if it made it and then keep on living in it.

For jarred honey with comb in it, how does that affect the hive?

They stay in the hive if it's not hot iirc

[–] Leeks@lemmy.world 2 points 1 month ago

Yup, if it’s cold they stay inside the hive and ball up! They vibrate against each other to make heat and stay warm.

Bees are so fricking cool.

[–] Leeks@lemmy.world 28 points 1 month ago (2 children)

Fun additional bee fact! Bee hives have personalities and each hive has a different one! Some hives are very easy going and have no problems being worked. Other hives don’t like to be touched and will get defensive quickly. When working hives, one of the things you look for is bees lining up on the edge of a frame staring you down. If you see that, hit them with some more smoke else you are about to be stung!

Bees navigate using the sun. It doesn’t really seem that they make a map, but more seem to know where they are by the process of directions that got them there. When they return to the hive they just reverse the way they got there. If you stand in front of the entrance to a bee hive for a few minutes then turn around to face away from the hive, you will see a swarm of bees flying in a holding pattern waiting for you to move so they can return. Once you move the entrance to the hive gets really busy. They don’t seem to know to go around you, they just wait till the path is clear!

You realize I would have you posting bee facts all day if I could, right?

[–] Leeks@lemmy.world 12 points 1 month ago (1 children)

Here’s another for the road: mites are a big problem for bees. They latch on to the bees and the bees don’t feel them. One way bee keepers can encourage bees to clean themselves and knock off the mites is by covering the bees in powdered sugar! This makes it look like there are a bunch of powder white bees flying around for a while.

Yea tobacco smoke I think but want to say they were being stopped for that n9t sure.

[–] kattfisk@lemmy.dbzer0.com 6 points 1 month ago (1 children)

I don't believe they'd use tobacco, as nicotine is especially toxic to insects (and has a long history of being used as an insecticide).

Beekeepers burn paper, woodchips, or really anything that burns well that they have on hand (that isn't toxic). Source: Have used smoker while handling beehives.

[–] tpyoman@lemmy.world 4 points 1 month ago (2 children)

That makes sense after reading up more I believe I'm wrong I feel like I'd heard that they used nicotine and hadn't fully researched and took it at face value. Thabks for the information!!

am i the only one who notices that this logic makes no sense? it doesnt matter that they have no lungs, they still are susceptible to both heat and airborn toxins, they perform gas exchange. They lived because the heat and smoke were below lethal toxic levels for them.

Next you're gonna tell me that plants don't have a neocortex!?

[–] Atomic@sh.itjust.works 37 points 1 month ago (2 children)

Insects don't have lungs. It also means their potential size is directly limited by the oxygen content in the air.

Which is why we don't see cat sized insects roaming around.

Which is why you don't see cat sized insects roaming around, I live next to a tarantula trail and some of them fuckers get BIG.

[–] WrenFeathers@lemmy.world 4 points 1 month ago (1 children)

Wait… tarantula trails are a thing?

[–] vaultdweller013@sh.itjust.works 8 points 1 month ago

Yeah they followed paths, I think it's a way of avoiding dangerous terrain. They are rather fragile beasts.

[–] samus12345@lemm.ee 11 points 1 month ago* (last edited 1 month ago) (1 children)

Spiders aren't insects. Though like them, they don't have lungs! Not ones like ours, anyway.

[–] vaultdweller013@sh.itjust.works 8 points 1 month ago (1 children)

In my defense I am a smartass not smart.

[–] samus12345@lemm.ee 4 points 1 month ago

Eh, you were close enough.
