Hi all,

attched is a pic of this years hatchling - it measured 152mm and is a male. Now even if it hatched yesterday 3rd july, take off 70 days for incubation (approx) and sixty five days for gravid period, that means that a mating must have happened around the 15th or so of February! I remember Alans post saying a grassie sighting on the 8th of February, so that must mean almost as soon as they emerge, they're at it! Enjoy this little fella, aint he cute!

Blimey that's early!

I've seen very two very small Nn under tins at work during the last week, which confused me greatly, as I assumed it was much too early in the season.

Is this year's juves the only likely explanation ?

I saw a few tiny neonates yesterday

Previous studies have shown autumn mating in grass snakes, also delayed fertilisation and spring hatchings have been observed in Europe.

That could explain it!

Steve /Mark,

Yeah, I must admit I thought it was a bit early as well. Maybe they do over-winter in the egg. Wouldn't that be amazing if that were the case. I can't remember, did we have a hot period in Febrauary?
