In P. mingo spot 4 & 5 overlap the other spots ie spot 5 overlap spot 6 ( not always), & spot 4 overlaps spot 3.
In P. trachala spots 4 & 5 do not overlap the other spots.

TL Seow: Cheers.
Thank you so much doctor Seow! Greatly appreciate this and helps me understand a lot better. Prior to this, i always look at the forewing spot 4 and 5, but found the overlapping part to be rather confusing as such. This has aid me in Identifying thw skipper much better until i get my hands on the C&P5 book!

Skipping regards
