larval abdominal seta
abdominal segments I to VII seta
In fourth stage larvae, a maximum of 12 pairs of setae are found on abdominal segment I, with setae 0, 8 and 14 presumed to be those which are absent. A maximum of 15 pairs of setae are found on each of abdominal segments II through VII. The sequential Arabic numerals applied to the setae of abdominal segments I through VII are believed to indicate serial homologies down the row of segments, ontogenetic homologies between the larval stages as well as with the pupa and phylogenetic homologies throughout the Culicidae.
