1914 W. E. Kellicott Textbk. Gen. Embryol. iii. 105 First, among many of the Crustacea, Annulata, Gasteropods, Cephalopods, and Amphibia, there is a process of pseudo-copulation or amplexus, where..the sperm are received by the female in or near the reproductive cavities or openings.

1953 E. W. Gudger in Amer. Midland Naturalist 50 200 My Ph.D. thesis (published in 1905) described the pseudo-copulation of the pipefish, Siphostoma floridae.

1958 H. B. Moore Marine Ecol. ix. 313 In many invertebrates either true or pseudocopulation occurs, insuring fertilization of all the eggs and thus avoiding waste.

1995 Economist 23 Dec. 122/3 Whiptail lizards in the Arizona desert practise virgin birth, though they perform a pseudo-copulation to get themselves in the mood.

2001 H. Schatten & A. Chakrabarti in J. J. Tarín & A. Cano Fertilization Protozoan & Metazoan Animals ii. 44 Most gastropods and cephalopods undergo internal fertilization after transfer of sperm by copulation, or pseudocopulation wth spermatophores.

2. Biology. An action or process by which a male bee or wasp attempts to copulate with certain orchid flowers that mimic the scent and often the appearance of the female insect, resulting (when repeated in successive flowers) in pollination of the plant.

1935 T. Rayment Cluster of Bees 144 I am invited to see for myself the phenomenon of insects effecting a pseudo-copulation with the flowers.

1969 Taxon 18 32 In common with all species of the genus, O[phrys] fusca and O. lutea owe their pollination to the remarkable process of pseudocopulation, carried out by male bees and wasps.

1998 S. Orlean Orchid Thief 46 Other species look like the mate of their pollinator, so the bug tries to mate with one orchid and then another—pseudocopulation—and spreads pollen from flower to flower each hopeless time.
