  abstract = {{R}eflex bleeding is an effective defensive mechanism against predators. {W}hen attacked, some insects emit hemolymph, which coagulates, quickly entangling their aggressor. {B}leeding occurs at weak intersegmental membranes or through dedicated organs, which can be associated or not with glandular cells. {H}ere, we describe the behavior and morphological structures involved in reflex bleeding in the larvae of the ladybird, {D}iomus thoracicus, which are intranidal parasites of the ant {W}asmannia auropunctata. {T}he larvae are tolerated by the ants thanks to odor mimicry, but some rare aggressive ant behaviors were observed that trigger reflex bleeding both at a pair of thoracic tubercles and a pair of posterodorsal abdominal humps. {N}o glandular structure was found in association with these emission points, which suggests that the material emitted was hemolymph only. {A} 3{D} reconstruction suggested that reflex bleeding seems to be controlled by muscles whose contraction increases the internal hydrostatic pressure and pushes the hemolymph into a funnel-like structure with an opening to the outside. {I}n {D}. thoracicus, the morphological structures involved in reflex bleeding are among the most complex and prominent described to date.},
