Attestations from sources in English: 

In Nahuatl hieroglyphs, the moyotl (mosquito) can sometimes look more like a fly (zayolin). The proboscis varies from a straight one, which could more likely penetrate human skin, to a curled one. See the search results for moyotl in the Visual Lexicon of Aztec Hieroglyphs. (SW)
