They wear their old heads, because they don’t have access to dead salmon.

That doesn’t make sense, caterpillars don’t mate. So why have a display like this? Or does this scare off predators somehow?

But why undertake this elaborate millinery? One study published in 2016 investigated this question by holding trials involving the caterpillars and their natural predators — spiders and stink bugs. The researchers found that attacks on larvae with a stack of headcases took more than 10 times longer than attacks on larvae that had had their stack removed. They found that the empty head capsules acted as a false target for predators and could also be used to deflect the piercing rostrum of a predator.

Oh really cool, thank you!

Put a stack of decaying skin on your head and see how appetizing you look to predators
watersnipje@lemmy.blahaj.zone 3 weeks ago
Yeah, fair. Maybe it’s just like that lizard that squirts blood out of its eyes and predators just go “EESH WTF”

Maybe it does nothing and evolution just never selected against it.
watersnipje@lemmy.blahaj.zone 3 weeks ago
It’s possible. Seems like it would at least change visibility to predators though. Or make it harder for the caterpillar to hide. Interesting!

Stupid caterpillar … it thinks wearing fancy head gear make it look sexier, more important or significant … what dumb animal would do that?

Taking off their molted head like it’s wearing nothing at all … (caterpillar booty shake) … like nothing at all!
