Hi ,

Most venation diagram depicts only the main veins, as Vein 8 and 9 are considered as branches of vein 7 , and also not all species has vein 8 &9 .

There are great variation on the present or absent of vein 8 and 9 across the sub-families

For Hesperiidae all veins on both wings are unbranched and run straight to the costal or distal margin.

For Nymphalidae forewing vein 8 & 9 are present .

whilst in the Lycaenidae's forewing some are with either vein 8 and 9 missing .
