For their study, the researchers obtained euthanized laboratory-reared female Aedes Aegypti mosquitoes, stored them in a freezer, then dipped them in a solution of 80% ethanol to sterilize them.

Next, the soft protective outer sheath of each insect’s proboscis was detached and discarded. An ultraviolet-curable resin was then applied to the now-exposed rigid section of the proboscis, and hardened by exposure to UV light. The resin-coated proboscis was then cut off of the mosquito’s body with a razor blade, forming a nice little rigid tube.

I can’t see it scaling very well.
