Hex Mayflies
Hexagenia limbata

Definition of 'abdominal setal areas'
Abdominal setal areas: Some caddisfly larvae have setal warts on first abdominal segment which are reminiscent of those commonly used for identification on the metanotum. They are similarly denoted sa1, sa2, and sa3, and may appear on both the dorsal and ventral surfaces of that segment. Both dorsal sa1 and ventral sa2 may be found on slightly raised, central bumps, whereas sa3 is always lateral. The boundaries between these areas are not always clearly delineated, if at all.
These other words reference the same concept: abdominal setal area, abdominal sa1, abdominal sa2, abdominal sa3.
