In larvae, the dorsal seta sequentially in line lateral to seta 2 on abdominal segment I; usually mesal to seta 4 (see seta 3-I-VII). In pupae, one of the two (usually noticeably paired with seta 2-I) dorsal setae occurring nearest both the anterior margin and the longitudinal midline of abdominal segment I; in most genera, interpreted as being the more posterior and/or lateral of the two; usually also the longer (see seta 3-II-VII).
