Thank you Anthony Paul & Tony and Jenny Dominelli for confirming the id of this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
Females are ~17mm long (head & body). A very long ovi-positor at ~8mm long, and even longer antennae ~17mm (as long as the body & head). Males are considerably smaller at ~12mm, with the antennae about the same length @ ~12mm (the same as the females in relation to body length)
The female antennae has a pale stripe in the middle that's missing from the male antennae. Notice the male is more chiselled looking, with more patterns (yellow & black). They have 3 toes.
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)."
We photographed 8 female specimens & 1 male in Oct, Nov & Dec.
