Abstract: | We studied the courtship and copulation ofFlorinda coccinea (Hentz) and described 18 behavioral acts for this species.F. coccinea exhibits many behaviors typical of the Linyphiidae such as web reduction, abdominal vibration, palpal jabbing, stridulation, pseudocopulation, and prolonged copulation. The numbers of palpal insertions during pseudocopulation and copulation are positively correlated to the durations of these phases. Pseudocopulation requires over three times more time on average than copulation, although females copulate longer than is required for fertilization. We found no correlation between the durations of pseudocopulation or copulation and fitness characters, and we hypothesize that lengthy pseudocopulation and copulation may function as a form of internal courtship. |
