I had imagined slakemoths as being somewhat larger.
Or tears. The expert on lachyphagous moths is Dr Hans Bänziger:
10 cases of lachryphagous moths settling at human eyes were witnessed. The behaviour of 3 Chaeopsetis ludovicae (Thyatiridae), one Rhagastis olivacea (Sphingidae) and one Togarishachia albistriga (Notodontidae) attacking the author is detailed. C. ludovicae was particularly obnoxious due to clawing of the eyelid’s conjunctiva. R. olivacea drank lachrymation while hovering, the tip of the 4-cm long proboscis causing little discomfort.
