Aaaaaaaaaa

Lash glue primarily consists of Ethyl Cyanoacrylate (ECA),¹ which is not toxic in small amounts. ECA is safe enough that it's even used in human medicine as liquid bandages or sutureless surgery.² Various types of ECA, including regular super glue, have been used as home-remedies for decades to treat acute injuries in arachnids.³ So gluing lashes to a scorpion is not dangerous.

There is, of course, a lot of anthropomorphism going on in this video, but I believe it's silly and exaggerated enough that it won't cause any misconceptions.

The only problem I can find with this video is that bug-handling on social media a double-edged sword. It's great PR and silly videos like this can genuinely help entomophobes overcome their fears. However, it can also spread the idea that handling all bugs is a good and fun thing to do.

While this scorpion is very habituated to being handled, not all scorpions will be as tolerant - and as with most bugs, scorpions do not enjoy being handled, they only tolerate it. Properly handling scorpions takes experience. For example, if they feel like they're about to fall, they will use their telson (or 'tail') to get a better grip - inexperienced handlers are likely to mistake this for a sting and can hurt the scorpion out of fear.⁴

Scorpions are happiest when they're left alone and allowed to hide all day,⁵ and I fear that videos like this might give prospective scorpion-keepers the wrong idea about these animals' personalities.
