next day and night. On the third morning, the frogs will leave the pond which has been filled with clutches of eggs. There is a preliminary calculated sex ratio of 12 males to 1 female. In general, reproductive activities were highest at the beginning of the rainy season and decrease rapidly after November. Mate Searching Behavior Males will make calls during the breeding season that consist of a series of short pulses (7-8 per second). The frequency range for these calls falls within 5.120 - 6.960 Hz. These males will move so that their vocal sacs are elevated so that females will be able to hear their calls. Mating occurs during most of the day but particularly from 8:00 pm to 4:00 am. The females that are attracted to the males will move into the water towards the males, and the males will then jump into the water to perform amplexus. The males do not vocalize during amplexus, and amplexus will last up to 30 minutes. Parental Care The Chiasmocleis ventrimaculata will lay their eggs on the surface of these ponds. Because of the explosive nature of their mating season, thousands of eggs can be deposited in one season onto these ponds. After hatching, these tadpoles will prefer the shores of the waters and tend to aggregate in these positions as a way to defend against aquatic predators. Social Behavior The frogs do not appear to care about living in groups and are not territorial. They have been seen living together with multiple frogs within one spider burrow. However, frogs do show high fidelity to the specific burrow which they originally selected and are never seen switching burrows. Even after the tarantulas leave the burrow because of the burrows becoming too inhospitable for the spiders to live in, Chiasmocleis ventrimaculata have been recorded to still live there. Mutualisms Commensal Relationship This frog is primarily known for its mutualistic relationship with the burrowing tarantula Xenesthis immanis. Whether or not the relationship is mutualistic or commensal still dominates conversations surrounding this species. It is clear the dotted humming frog greatly benefits from this relationship, as the tarantula provides the frog protection from predators, a stable food source due to the frog’s ability to feed off the remnants of the spider’s prey, and shelter to protect from climate changes. On the other hand, the frog's foraging protects the tarantula's eggs from ants. The
