Resumen:
Currently maternal attendance in L. bolivianus is not well understood. Herein I report attack behavior observed in three different females of L. bolivianus. All females tested were guarding tadpoles. Females would suddenly attack a meterstick that I was holding near the head. I presented each of the three females with a rubber ball attached to a 40 cm stick. Two trials of 15 presentations each were made. I recorded the female's response (attack or escape). The frogs jumped from a distance of 30-40 cm away toward the ball, knocking it with their heads or pushing it with their hands. The female responded in the same manner to stimuli suspended over their heads. Ocasionally, females performed bouts of the pumping behavior prior to attacking the rubber ball. This behavior was highly variable among the females tested. I recorded 58 attacks of the model  by the three females. Females detected during the day were always completely hidden. Any attempt to present the rubber ball was followed by escape or no response. In contrast, females of L. ocellatus in Uruguay, Goias, Brazil, and C√≥rdoba, Argentina attacked during the day.
