The use of pictures from the internet as data source for more better distribution maps is demonstrated. Based on pictures within the database www.lacerta.de and using the only known field character “greenish throat colour in hatchlings” first records of Lacerta bilineata in Carintia (Austria) can be stated. And it is shown, that this character is obviously also useful to distinguish the L. bilineata of the “West Balkan clade” (W. Böhme et al. 2007) and L. viridis in the lowlands of Thessalia (Greece). These findings should motivate intensified field herping activities and in case of green lizards more pictures of hatchlings instead of large blue throated males.

A short introduction and a hypothetical model concerning color formation in lacertid lizards is presented. Thereafter we observe and discus the ontogenetic changes in a single female captive bred Podarcis pityusensis lizard from Formentera (Balearic islands/Spain). Striking transformations concerning coloration are observed.
This is already our sixth report in a series on our whereabouts while collecting data for a future revision of the present subspecific order of the endemic Balearic sisterspecies Podarcis lilfordi (GÜNTHER, 1874) and Podarcis pityusensis (BOSCÁ, 1883), which data are stored in our database at www.pityusensis.nl (VAN DEN BERG & ZAWADZKI 2011 ; VAN DEN BERG et al. 2013 ; VAN DEN BERG et al. 2014a ; VAN DEN BERG et al. 2014b ; VAN DEN BERG et al. 2015). During this trip from the 27th of March until the 9th of April 2016, we were able to collect data at some mainland Ibiza locations, as well as on the following adjacent islands: Sa Mesquida, S’Hort, S’Illeta de Cala Salada, Vedranell, Rates, Bleda Plana, Murada, Bleda Na Bosc and S’Espardell de S’Espartar. We continue with the ventral coloration as a possible determining key as introduced in our 2014 trip report (VAN DEN BERG et al. 2014b). Images of the anal shields are presented of each lizard for purposes of illustration.

From 20.4.-26.4.2015 as well as from 14.4.-26.4.2016 we visited the Canary Island of El Hierro. Our particular interest was directed towards the El Hierro giant lizard (Gallotia simonyi) and Boettger’s lizard (Gallotia caesaris caesaris). With our pictures of the Mediterranean Tree Frog (Hyla meridionalis) from the plateau near Tiñor, we are finally able to give proof of its existence on El Hierro.
