Blest & Taylor (1977) noted that when the cephalic sulci of male Baryphyma pratense (Blackwall) are gripped by the fangs of females during copulation, the male heads bleed and the females ingest the blood. It has recently been suggested by Schaible, Gack & Paulus (1986) that ‘blood’ may in fact have been the secretion from the cephalic glands associated with the sulci. The early account is expanded, and the reasons for supposing the material to be haemolymph listed. Cephalic bleeding by males of B. pratense is suggested to be unusual, and to represent both a bizarre variant of courtship feeding, and a form of male parental investment.
