Posted: 11 Aug 2008 [QUOTE=grenouillaire] How can i tell if I'm looking at Bilineata or Viridis or are they (as some websites suggest) one and the same ? [/QUOTE] Hi Grenouillaire, if the photos were taken in France then they are Lacerta bilineata. I got the map below from the net, and it shows the distribution of bilineata in green and viridis in blue. There is a rather confusing 'hybridisation zone' in NE Italy and Slovenia (yellow on map), which various reseachers have assigned to either viridis or bilineata. As to whether viridis and bilineata are distinct species, evidence would suggest they are, as although hybrids do occur in nature they show reduced fertility. cheers.

Hi Axel Thanks for that. Bilineata it is then (taken in France) - what it is to be in possession of a little bit of knowledge. One other question then - what do these guys eat ?

Posted: 13 Aug 2008 Green Lizards will feed on large invertebrates from Locusts, grasshoppers, through Spiders to Earthworms and have even been known to feed on small lizards when they can catch them. In regard to the distribution map shown above there is a paper by Bohme et al 2007 available to people registerd on the Euroherp Database http://nemys.ugent.be/start.asp?group=16&c=1 which has results showing a Lacerta bilinetalineage in the western Adriatic going from N.E. Italy & Slovenia down to N.Greece on the Adriatic coast. This of course has nothing to do with the French population.

Thanks for your post David As you can tell I'm a bit new to all this and coming across many species that I have never seen before. Below is a photo of (maybe) said lizard's lunch then !!! At about 7cms+ would they be a bit big ? I'm keen to encourage the reptile population (and any other wildlife for that matter) so any input that I can gain so much the better.

Finally got to photograph my Green Lizards. But my total lack of knowledge is again leaving me slightly confused. How can i tell if I'm looking at Bilineata or Viridis or are they (as some websites suggest) one and the same ?
