The host is now completely cloaked in Melittobia larvae … just its head is visible (to the right). Perhaps the feeding parasites can’t effectively penetrate the tougher cuticle of the head capsule. There is so little room that some of the grubs have been pushed away from the host by their siblings.

Compare this scene to that just 6 days before … noting that no new eggs were laid in the interim, as no adults had access to the host. Wow bugs indeed!
