Wolfgang, thanks for the confirmation. For the non-expert how can you tell V. seoanei and V. berus apart? Steve |

Posted: 05 Aug 2008 In this case very easily - V. seoanei is the only one found in northwestern Spain and northern Portugal, V. berus does not go further southwest than Brittany and the Massif Central. Specimens without locality information can be very difficult. Indeed, V. seoanei used to be considered a subspecies of V. berus for a long time (and any reports of V. berus from Spain or Portugal actually refer to V. seoanei).

Posted: 05 Aug 2008 They also have a different mating regime, mating in autumn, and also exhibit long term sperm storage unlike berus. 'I get my kicks on Route 62' |

I have just seen this. I think it is an adder, but I'm no expert. I'm in San Sebastian, Northern Spain.
