像成年人一样，幼虫的myrmecophilous瓢虫瓢虫Coccinella magnifica很少被攻击的Formica rufa蚂蚁的觅食路径，但更经常攻击蚂蚁照顾蚜虫殖民地。七星瓢虫（Coccinellaseptempunctata）的幼虫，其中七星瓢虫C. magnifica相比，在这两种情况下更容易受到蚂蚁的攻击。为了避免或对抗蚂蚁的侵略时，蚜虫觅食，C。magnifica幼虫表现出三种主要策略：它们可能以无人照料或无人照料的蚜虫为食;当以有人照料的群体为食时，它们往往把猎物带走，尽量减少在那里停留的时间;如果受到攻击，它们使用有限的化学防御。在C. magnifica幼虫，在C.七星花大瓢虫卵被放置在远离蚂蚁倾向的蚜虫，虽然接近联合国或非倾向的蚜虫。
Like adults, larvae of the myrmecophilous ladybird Coccinella magnifica are rarely attacked by Formica rufa ants on foraging trails, but more often attacked on ant-tended aphid colonies. Larvae of the non-myrmecophile Coccinella septempunctata, to which C. magnifica was compared, were more readily attacked by ants in both situations. To avoid or counter ant aggression when foraging for aphids, C. magnifica larvae exhibit three main tactics: they may feed on un- or non-tended aphids; when feeding on tended colonies they often carry prey away, minimising time spent there; and if attacked, they use limited chemical defence. No novel behaviours were found in C. magnifica larvae, not occurring to some extent in C. septempunctata. Coccinella magnifica eggs were laid distant to ant-tended aphids, although closer to un- or non-tended aphids.
