Thanks to Thomas Mesaglio, from our facebook group, who gave us a really amazing insight into these wasps:
" 'Orchid dupe' refers to the orchid species Cryptostylis leptochila, which looks similar to the males of Lissopimpla excelsa and tricks them into attempting to mate with it (and thus pollinating it)."
