Urticae used to be very common, but seems noticeably less so in the last decade or two. One of my most vivid childhood memories is of urticae covering pink ice plants in local gardens. I have encountered urticae at very high altitudes of 2000m plus and with temperatures as low as 12C, when it has been the only butterfly on the wing (perhaps not surprisingly). Interestingly, urticae has much the same blue marginal marks the Camberwell Beauty (Nymphalis antiopa).

It occurs throughout France but is described by the Lafranchis France book as rare in the south-east and the Mediterranean region. I would concur with this, hence the lack of photographic opportunities.

 

In the UK, there has been a dramatic decline in the numbers and this has been the subject of considerable research in recent years to determine the cause. It is believed to be because of attacks by a tiny parasitic fly, Sturmia bella. However, in the past few years there does seem to have been a sort of degree of recovery of the numbers, although not fully reaching the numbers of a decade ago.

37587 M a very fresh male, with rather limited black markings in the uph basal region, suggestive of the subspecies ichnusa, which it cannot be as this subspecies only occurs in Corsica and Sardinia. It has a very appealing deep fiery orange red colouring. 370

M I suspect this is a male on the basis of the end of the abdomen and the body length, but the sexes of many vanessids are very similar.

F I am guessing that this is a male in that it is taking salts rather than moisture.
