Couldn't find any larva at all, then found out about the secondary pet method. First secondary pet larva was rare and caught it. Then used spirit crabs for an uncommon, but while I found a larva here and there, didn't find a green one (though it did appear that someone had gotten nearly all the +lvl 5's before me).
I then moved inland, hunting down all the +lvl 5's I came across and soon I got an uncommon larva secondary over in Deatholme.
