The typical sequence of dragonfly mating includes tandem formation, intra-male sperm translocation and copulation, which is followed by oviposition. Minor variations of this scheme exist, as e.g., when sperm translocation is not performed between tandem formation and copulation (J.K. WAAGE, 1973, Behaviour 47: 240-256; A. KUMAR & M.PRASAD, 1977, Odonatologica 6: 163-171; C. UTZHRI, 1985, Odonaiologica 14: 227-238). In accordance with what is most frequently observed in dragonflies, in Lestes barbarus sperm translocation is performed only once after tandem formation, even though copulation can be interrupted and resumed several times (E. LOIBL, 1958, Z. Tierpsychol. 15: 54-81; C. UTZERI et al„ 1987, Fragm. enlomol. 20: 1-22). Nevertheless, we are herewith reporting on two exceptional observations of repeated intra-male sperm translocation in this species. 28-VII1-I975. — The tandem male translocated sperm to the accessory genitalia according to the usual pattern (UTZERI et al„ 1987, ibidem), then the female attempted to lay eggs, but the pair shifted to another perch and the male again translocated sperm, after which copulation followed.
