I think you've cracked it
MANUCODE is an anagram of 'cameodun(s)'
'appearance under the fig tree' would be a reference to habitat / diet . .
I presume
Can't work out where the 'et' comes from though
I was going down the "BUSH Track" . . so to speak
Well done in solving what I regard as a VERY tough one
