Writtle Wildlife Watch (June 2014)

Writtle Wildlife Watch returns for June! Alan Roscoe is at it again and once more keeps track of the fascinating wildlife on campus! 

--------------------------------------------------------------------------------------------------------------

I hope most of you caught up with the recent Springwatch programmes from Minsmere. Apparently the visitor numbers were up a staggering 50% as a result of the TV coverage although you do have to wonder whether the additional visitors were more excited about seeing Chris Packham than the wildlife!

It is good to see the BBC committing so much resource to programmes like this although (curmudgeonly grouch face on) just occasionally I wonder whether there is an overemphasis on the birds and the mammals – which, of course, the public enjoy – at the expense of the plants and other groups such as lichens and mosses. These are just as fascinating as the popular animal groups but, perhaps because they do not move, they are less appealing to the general public.

We monitor a range of animal species on our own College estate but we also keep an eye open for unusual plants and now is the best time of year for many orchid species. We are lucky enough to have both Bee Orchid and Pyramidal Orchid on our estate and, due to the sharp eyes of a colleague (well spotted Roy), we have found a new site for them this year. Pyramidal is pollinated by moths and butterflies which visit the plant not for nectar, but for a watery liquid which is found inside the ‘spur’ part of the flower. Grains of pollen are then picked up on the insect’s tongue and the perfect symbiosis of this particular species and its pollinating insects was even remarked upon by Charles Darwin himself.

Writtle Wildlife Watch (April 2014)

Writtle conservation expert, Alan Roscoe, has once again been observing the wildlife on campus at Writtle. Here, Alan reviews his April findings.

"Now come on, this just isn’t playing fair. One second you think the rain has gone and we are in for another scorching summer like last year, the next you are gazing out of the window, whilst reaching for the thermostat.

But did you notice the slightest warming of the days a few weeks back when things started waking up? We certainly did here at the College as we are interested in annual changes in seasonal events (’phenological indicators’) and our students keep an eye open for us on the first appearance of certain key species, especially butterflies.

So, what was the first butterfly out of the blocks this year? The Brimstone was the first species, spotted in late February by our student Fiona basking on bricks near the student restaurant (the butterfly that is, not Fiona). This sulphur yellow insect was closely followed by Peacock, Small Tortoiseshell and Comma. But for me the acme of spring is the Orange Tip. This small butterfly says that spring is in full swing and its appearance is all the more special for it being so fleeting.

Thanks to our student Noah for this great picture of a female Orange Tip on the College estate. Roll on summer."
