They breathe their own farts. Well.

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.

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

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.

don't beekeepers use smoke or some such?

[–] tpyoman@lemmy.world 0 points 7 months ago (1 children)

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

[–] kattfisk@lemmy.dbzer0.com 0 points 7 months 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.

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!!

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.
