A. friderici feed on the oil palm & seem to be increasingly common but confused with A. phidippus.
I was shown several examples of A. friderici by Liew of Raub.
One example was surprisingly very similar to A. phidippus on the underside & upperside. Liew assured me the abdominal hairs are bicoloured.
It seem to be exactly like the specimen in the Singapore Biodiversity Website.
The UnH 4th band is only lightly notched ,the head end large but the sides rounded . https://singapore.biodiversity.onlin...doptera-000251
The upperside is also more orange than typical [I]A. phidippus.
There is thus a strong suggestion that the set specimen in the website is also A friderici.
