Acerocephala hanuuanamu stinging C. brasiliensis and host feeding in phloem sandwiches a stinging a C. brasiliensis larva. The ovipositor is visible extending nearly the length of the wasp’s gaster within the larva b subsequent host feeding on the same larva as in (a), on the same spot where it stung the larva c stinging a C. brasiliensis pupa through its hard pupal chamber after excavating the loose debris outside the chamber. The ovipositor is visible in the empty space between the chamber wall and the pupa d subsequent to stinging the pupa in (c), host feeding through the wall of the pupal chamber. Part of the feeding tube is marginally visible protruding from the pupa as a small bump between the pupa and the interior of the chamber wall, on the part of the pupa most proximal to the mouth of the wasp e probing with the ovipositor to find the pupa inside the chamber. The ovipositor is visible extending towards the pupa within the chamber. This attempt by the wasp was unsuccessful due to the position of the pupa within the chamber f an additional subsequent feeding event by the same wasp on the same pupa. The gaster is distended and the liquid periodically excreted by the wasp as it feeds is visible just past the end of the wasp’s gaster.
