LOOKING FOR Armoured Ground Crickets / Koringkriek

I'm an Orthoptera collector and absolutely fascinated about ARMOURED GROUND CRICKETS. I do not know a lot about the climate and seasons in South Africa, but I would like to ask if someone can provide me with dead, dried specimens of the mentioned crickets. I am looking for these interesting and uncommon creatures to enrich my orthoptera collection. I am grateful for any help to find other collectors, dealers or hunters for "Koringkrieks / Dikpense" who can provide me with good quality specimens.
Thankyou, Michael (francisento)
