"The nasal botfly (, : ) is a myiasis-causing insect species, which affects the health of sheep, goats and humans. Gravid females are viviparous and larviposit into the animal’s nostrils. Host-searching and larvipositing flies are visually guided and influenced by climatic conditions, whereas olfaction seemed to play no role in this process. However, here, we show that the antennae of adult O. ovis female flies are relatively small but well developed and inhabited by several types of olfactory sensilla. Further, we show that the antennal lobes of this species receive input from antennal afferents and consist of a clearly defined glomerular organisation. We also give the first evidence of the fly’s ability to detect several synthetic odour compounds."
Botflies, also known as warble flies, heel flies, and gadflies, are flies of the family Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. Dermatobia hominis is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans.
"... the way mosquitoes serve botflies in Central and South America. The size of a , the fly seizes a mosquito in midair and glues her own eggs to her captives abdomen. Later, when the mosquito feeds on a person, the damp warmth of human skin causes the flys eggs to hatch, leaving maggots to burrow into the new host. Soon, the maggots breathing apparatus can be seen poking through the victims skin. Within a week, its as large as a small olive."
", commonly known as the human botfly, is native to Tropical America. As such, cutaneous infestation by its developing larvae, or myiasis, is quite common in this region. The distinct dermatological presentation of D hominis myiasis allows for its early recognition and noninvasive treatment by locals. However, it can prove quite perplexing for those unfamiliar with the lesions unique appearance. Common erroneous diagnoses include the following: , , and embedded with localized ."
