Jersey in Crystal Palace?

I was somewhat surprised today to see a Jersey tiger  (Euplagia quadripunctaria) moth on a Butterfly bush in Crystal Palace park. Apparently, there has been a breeding population in South London since 2004. My picture will follow when I return from holiday.

Seeing the Changes 918

Given the fact that I am off again to Sikkim in early October, it was striking to note the masses of alien Himalayan balsam (Impatiens glandulifera) in the Clyne woods. Some of the flowers were white rather than the usual pink.

A Ruddy Shame?

It has been announced that the end for the north American Ruddy duck in the UK is (almost) nigh ( The duck was inadvertently introduced by Sir Peter Scott via his Wildfowl and Wetlands Trust establishments but male of this species proved irresistible to endangered European White-headed ducks with whom they hybridised. This resulted in the 'over-sexed' aliens being eradicated. Apparently, the last 10 females are due to be shot at £3000 a pop (an expensive business this antipathy to aliens!).

It Doesn't Adder Up!

There is a report of a man bitten three times by an Adder (Vipera berus) that he picked up being seriously ill in hospital ( As the article confirms, the snake is Britain's only endemic poisonous reptile but its venom is largely produced to enable it to subdue its prey (including things like Field mice). The snake is largely secretive and, under these described circumstances, would have been operating in a defensive mode. The article also confirms that wasps and bee stings have killed many more people than the Adder in this country. I do hope that this story does not lead to increased attacks on snake-like animals (I have encountered people who have whacked Slow-worms with spades). The Adder is actually a useful and beautifully-crafted addition to the UK fauna.

Visited, in Loughor, by a Forest bug (Pentatoma rufipes).

DQ to Replace IQ?

It has long been apparent that the digital competence of even the youngest UK child is light-years ahead of most adults in this country ( So it has been suggested that we ought to measure DQ (digital quotient) rather than IQ (intelligence quotient). The current generation apparently feel that they would be lost without their mobiles and/or tablets, spending much more time on line than watching TV (this is what the old folk do). Their modus operandi apparently changes how they interact with people, how they take in 'news', how they watch programmes and films, how they listen to music etc. Unlike the current generation, they rarely use email. All this may appear slick and a bit 'brave new world' but a) they may not always receive 'balanced' information and could prove more susceptible to external control b) they would certainly be more dependent on their digital suppliers and c) there is likely to be a very intense digital divide between the 'haves' and the 'have nots'. Some of these features are likely to be even more intense in other parts of the world. Now, I must 'phone my grandson to help me post this.

When Penguins Stalked the Earth

Some 37 million years ago, a giant species of penguin, up to 2 metres tall, apparently roamed the icy wastes of Antarctica ( These impressive birds were much larger than the current record holder (the climate change-endangered Emperor penguin) and it has been calculated that they would have been able to stay submerged and fishing for up to 40 minutes. Presumably, this foraging advantage was more than countered by some disadvantage of the large body size (perhaps reduced ability to change direction?). Anyhow, they would have been an impressive sight.
