Thanks Joan, I did go back and gave it a read. I'm familiar with Steve Woodhall, he published some of the butterfly books of SA.
I need to actually learn more about the butterflies in different areas, I only know the Cape Town ones really well from butterfly surveys.
Work associate of 19 years Allan Plowes had an interesting large collection, enthusiastically shared knowledge,
I believe his collection was donated to the Lepidopterists’ Society of Africa by his son before he moved to the UK. Acknowledgements to Allan Plowes in "What's that Butterfly?: A starter’s guide to butterflies of South Africa" By Steve Woodhall
