It's a hoverfly, I have no idea what flavour ...........

What I do know is that with a 420mm lens combination it was quite a challenge and this is, in my opinion, a pleasing result given that with a fairly long lens, hand held photography of a pretty active subject is a real test when it comes to camera shake. 

Window web weaver .......

I am absolutely clueless when it comes to spider identification, all I can tell you is that this guy is literally hanging about outside my dining room window.

Siting his / her web here is strategically a questionable decision as every time there is a strong wind or heavy rain the web gets damaged and it seems to spend a considerable amount of time effecting repairs.

Please, if you know what species of spider this is leave a comment, it would be much appreciated. 

What a web we weave ............

The rain today put paid to any outside activities so I would like to recount something that I came across on the reserve mid-year.

Wondering around I happened to look up and see the above web in a tree,  my immediate thought was what sort of tree spider would build such a strange web ? ...... I was intrigued.

I searched the web without any luck and in so doing came across the details of the Royal Entomological Society at St Albans so I sent a copy of the image to them on the off chance that they would respond and basically forgot about it.  

Several days later I received an e-mail from a Professor Jim Hardie, Director of Science at the Society and a dialogue commenced, what habitat, what tree species etc etc.

I have never been very good with tree identification although I was pretty confident it was a willow ( to the left of the Heronry Hide ) so on my next visit I got some leaves, photographed them and sent the image off to Prof. Jim.

The response was quite a surprise, the web was not a spiders  but a caterpillars !

'' Hi John, It seems very likely that your webbing was produced by caterpillars of the willow ermine moth, Yponomeuta rorrella. It’s a pretty little moth and  http://ukmoths.org.uk/show.php?bf=428 gives some information.

Best wishes

Jim

What a great end to the story, I thanked Prof. Jim profusely for his time, interest and efforts, a thoroughly rewarding exchange with a very capable academic and his team.
