Miss Croft, there are numerous entries in Herpetofauna of observations of Stophurus and Oedura licking nectar and saps. At a recent talk at the AHS, Glen Shea, did a talk on field work around Norfolk Is, which he did with Harold Cogger. The outcrops around the island hold vast, and I mean vast! numbers of Christinus guentheri, these Geckoes were found to be mainly living off a diet flowers for most of the year. I personally think more work needs to be done on the captive diets of these types of geckoes as they seem to consume some amounts of sugar in the wild that we are not reproducing in captivaty. Also of note from that talk, some eggs taken by H. Cogger and incubated, took nine months to hatch!
