    Posted: 12 Jun 2012 at 11:33am
I was recently asked to photograph a Hybrid newt captured during routine crested newt surveys at the Durrell Institute of Conservation & Ecology, University of Kent. The newt was captured, 7th/8th June 2012, in a bottle trap in one of the Farmland ponds which forms part of a long-term monitoring project, led by Professor Richard Griffiths and a team of volunteer surveyors. 

The general features of the hybrid newt include those shared by L. helveticus, a dorsolateral ridge, small tail filament, partly-webbed hind feet, double row of spots on tail, eyestripe and marbling on the head. Also features shared with L. vulgaris, a spotted throat, large spots on belly and flanks, crest continuous with tail, orange belly, lacking hind foot spurs. These are all features that were observed by Griffiths et al. in a paper published in the Journal of Zoology (1987). The paper was titled - A natural hybrid newt, Triturus helveticus x T. vulgaris, from a pond in mid-Wales. 

These newts are observed infrequently and are seldom recorded, however I have been corresponding with several colleagues who have also shared their encounters including a recent capture by Paul Hudson (Penrith, Cumbria). 

I would be interested to hear of others who have encountered these hybrids and indeed any images you might have. 

Here is the newt -

That's great - please feel free to PM me with any dates and locations (Grid ref).. Might be worth compiling for a short publication..? If you're not sure of exact date, I suspect it's attached to the photos somewhere.

Kind regards,

Brett

Yes, I've been wondering about a publication for a while. I know that Brian Banks has found a couple in Sussex.

I've seen photos of Paul's and his is quite different. Maybe he'll post them?

Come on Paul!

The smooth/palmate hybid that I found here in the garden pond ,returned each year for 7 or 8 Springs .I never saw it displaying to a female during my many torching sessions of the pond ,often there were females in close proximity to it but they were always ignorned . Maybe it didn't look and smell right to the females or it somehow lacked the urge.I'm fairly sure I saw another Hybrid one night whilst torching a large stocked fish pond near to Kendal .Unfortunatly that one slipped the net .Perhaps there are plenty more out there and some folk would not be able to I.D them.

How common do people think this is? As common as the two co-habiting or are there any known limiting factors? I have to say i don't tend to examine male Palmates in that much detail but will keep my eyes open from now on.
Cheers
