Mosquito larvae do have relatively large eyes relative to body size. MOSQUITO LARVAE are called WRIGGLERS and MAGGOTS in English due to their twisting, screwing movements. In addition to congenital defects and emergency surgical procedures at birth performed to save the life of the mother, deformed children were also caused in dynastic China as a direct result of「rolling」during the foot-dis-integrating process as a botched job of turning one's prepubescent daughter into a concubine or service provider for future sale. Some folks were trying to make a few extra bucks by doing-it-yourself and not calling upon the local shaman with all her experience, trying to use the blunt side of a mattock head or a large rock on the soles of her feet. Unfortunately, that process also created many DEFORMED CHILDREN, especially if the young girl was a WRIGGLER who contributed to the mishap by not holding still, to become a meat sack MAGGOT who crawled and could not walk (note the given external source definitions of LARVAE, sacks of boneless meat squirming along the floor). In fact, the shaman and her skills also created deformed children, but as meat sacks for which wealthy men were willing to pay hard cash specifically to acquire those deformities, as long as the deformed feet were symmetrical, free of bone splinters, and without large external scarring (…what a world). As depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis:「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)

　「Viewing women as commodities [see 品] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

　「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　Or: initially, a MONSTER was「a term formerly used to denote a fetus or infant with such pronounced developmental anomalies as to be grotesque and usually nonviable. More appropriate terms [in today's parlance] are congenitally deformed, malformed, or abnormal fetus, especially when discussing these individuals with loved ones」and「Relating to anything–e.g., a cell or entire organism that is strange, bizarre, freakish, or extremely unusual. A popular term of waning popularity for a person with severe external malformations. Freak」　[　https://medical-dictionary.thefreedictionary.com/monster 2020-06-29　]　
　Perhaps the Chinese sages were issuing a warning of what creates a MONSTER, with a merging of the elements「raised rod」with「child」that could refer to either or both the pedophile and child at the time, or the child after becoming an adult, all suffering the consequences.
　「One-armed or one-legged child (or both)」as DEFORMED CHILD, a MONSTER. The English term「monster」formerly referred to deformed human babies and infants, which was/is not an altogether uncommon occurrence.
