Exactly what I was going to say! Its coming into the season where most animals are now going to think about procreating, if he's that desperate and has no other option he may well attempt to get the other frog into amplexus. My whites have not done it to one another but they have been very restless recently. My male Firebelly is calling non stop and as soon as one of the others go past he jumps onto them, both the male and female.
