i have 6 leaf insects in all (2 female macley spectre, 2 female phillium siccifolium, and 2 baby phillipines) at the moment i have the macleys and the siccifoliums living on a mixture of bramble, oak, rose and ukaliptus plants, they are not housed in enclosure. the two phillipines live in a small cricket tub at te moment as they are too small to be on the open plants. when the phillipines re big enough would it be safe to have them all on the same plants ???
