Hallo Michael,
Hallo ihr Stinkmorcheln,
"Finally, the trap mechanism is
not ‘‘absolute’’ like in Arum where attracted
flies are trapped for 24 h within the floral
chamber. In the dead horse arum, blowflies
were observed coming in and out from the
floral chamber, because there is no efficient
physical barrier as in other Arum species."
