Conratulations Ashton
Yeah definitly try fruits, i've been trying to find out what are most common in S.Asia/Northern Australia, but no luck yet, but i've just remebered (while writing this) that one of my cousins lives there, so will ask and let you know
sorry to hear about ur queen

is that colony now queenless? they are an 'advanced' species tho, so culd be the tiniest thing that kills her
yes my colony is coming from Kalytta, its not 100% confirmed as Affinis, but its very similar, if i cant work it out, i'll take a worker or two down to the natrual history museum an rumage thru their specimins, if they'l let me lol
