Comments

2* A. callidryas taylori occurs in the Yucatan Peninsula. Savage and Heyer (1967) argued against recognizing subspeices. Funkhouser (1957:34) used differences in size and proportions to distinguish two subspecies of A. callidryas, of which A. c. taylori occurs in the Yucatan Peninsula. Savage and Heyer (1967) argued against recognizing subspecies. Duellman (1970:111) noted that northern, central, and southern segments are recognizable within A. callidryas but declined to afford them nomenclatural recognition pending the acquisition of material from critical areas.

Life History

Life History Narrative

These common and colorful frogs are nocturnal inhabitants of lowland tropical forests. They are arboreal and generally move through the vegetation using slow, graceful, hand-over-hand movements. During the dry season they hide in arboreal vegetation such as bromeliads and palm fronds (Stuart, 1958:18). Reproduction is initiated by the onset of the rainy season, and the males congregate in choruses of a few to hundreds and call from trees and shrubs surrounding temporary bodies of water. Calling generally begins about dusk, and the males usually sit perpendicular to the axis of the stem or twig from which they are calling. The females are attracted by the vocalizations and approach the males. Amplexus is axillary, and the eggs, about 20 to 50 pale green eggs per clutch, are deposited on vegetation overhanging the water. Pyburn (1970:211)observed breeding in southern Veracruz and reported that amplectant females descend to the water and fill their bladders before ascending to oviposit. As eggs are deposited, they are hydrated by water released from the female's bladder. Females deposit multiple clutches, descending to fill the bladder before each oviposition. Pyburn (1970:212) observed male-male aggression in which nonamplectant males attempted to displace amplectant males. In some instances more than one male fertilized a single egg egg clutch. On hatching, the larvae drop into the water, where they complete their development. The tadpoles of A. callidryas are known to feed on the larvae of other species of frogs (Ryan, 1985:47).
