(Johnson, 1966) have not revealed differences be- tween age classes. However, distinct dietary differ- ences between juveniles and adults have been reported for Takydromus tachydromoides (Jackson and Telford, 1975). They found juveniles to feed equally on spiders and insects, whereas in adults the biomass of insects taken was three times that of the spiders. The difference was attributed to a possible preference by juveniles for soft-bodied prey and the almost total lack of availability of insects in late fall and early spring when adults were relatively inactive compared to juveniles. Differences in the jaw mechanism of adult and juvenile Agama hihroni have been implicated in dietary differences between age groups (Capel- Williams and Pratten, 1978) with adults eating mainly Orthoptera and juveniles mainly Hym- enoptera and Formicidae. Paulissen (1987) re- ported that adult Cnemidophonis sexliiicatus pre- ferred grasshoppers and avoided plant arthropods whereas juveniles had a reversed preference for the same groups. Schoener (1971) predicted that food size should decrease with decreasing predator size within a species. This prediction was borne out in Takydromus tachydromoides (Jackson and Telford, 1975) and also xnAgama tuhercidata in the present study. Ants eaten by hatchling/\. tuhcrcukita were exclusively of the smallest species available.
