First sightings this year for me. A couple of days later than the previous two years. Lizards sheltered against the wind which is still bitterly cold.

Also managed a couple of Adders this afternoon. Feels like things are finally moving again on the south coast.

Excellent sand lizard spot - very jealous! amazing how dull they look on emergence..

Thanks Will.

This site has traditionally early risers as far as I'm concerned. However another nearby 'early' site still quiet after another check this afternoon. The problem being they are so easy to overlook when first emerged due to their earthy appearance.

Still waiting on ZV here, which by my very amateurish calculations could be at least another two to three weeks.

interesting that La are early to bed for the year (mid August in some cases) and also early to rise the following spring.  I usually expect Zv out and about along with the first Vb, but as yet haven't seen any Zv in spite of apparently suitable weather.

Will why would they hibernate mid August? Seems incredibly early, and lots of hot weather still possible - likely even! What would be the advantages to the species in doing that?

A very good Q! it has been suggested that it protects the hatchlings from their cannibalistic parents, but this argument is species-selection/group selectionist and doesn't hold water. This is because any adult that 'decided' to stay above ground would be able to feed up on the hatchlings and its genes would be passed on more effectively into the next generation, ie the 'hawk' strategy would triumph over the 'doves'. So there must be an advantage to the individual lizard in terms of its own lifetime reproductive success, but it does seem strange since there's often a glut of insects on the heath in September (crane flies etc). We need an expert on this - over to Chris??

An interesting point raised here. I will have to pay more attention to the final sightings of the year, as well as the first.

It certainly seems that they just drop off the radar quite early on. I thought maybe the increased vegetation cover meant they were harder to see.

As Suzy asks, "What would be the advantages to the species in doing that?" ?

I'm guessing it's an energy budget thing; maybe there just isn't enough food to give them a decent chance of survival in the coming winter, whereas going underground in late summer / early autumn makes more sense energy-wise. I wonder if this links in with the 'adders underground' thread - ie perhaps it remains cooler than one might think below ground on the heaths. I do think this is a genuine phenomenon rather than observer bias, given that autumn is a great time for spotting other reptile species on the heath (including smooth snakes) and also hatchling sandies.

After checking this morning, Sand lizards now out at a second site in the area.

Well Done RAGS,

In order to balance my annoyance at not finding the first Sand Lizard of the year! I shall trump your picture with this little fella enjoying yesterdays sunshine. In addition had two adults and loads of common lizards, though they were a bit to active to snap.

Well SteveA.  I feel you may have trumped me good.

But don't reach for the pot yet...

My 'little fella' was photographed on 27th February 2015.

9th April.
The recent few warm and sunny days have resulted in some very bright and perky adult males. Also the males and females are beginning to pair up.
