Moths & Bats Saturday 30 th August 2014

Moths and Bats


A successful evening was had on the reserve with 51 adults and children. Robin Dalton Countryside Manager gave an excellent introduction to bats for the youngsters. I am sure I speak for many in Thanking Robin for so unassumingly giving his time into the small hours and helping with the prep work in conjunction with CBWG  in making the event a well attended an interesting evening and Calderdale are fortunate in having such a committed Ranger on the Team . Thanks also goes to local naturalist Andy Cockroft whose expertise is much valued and appreciated . and CBWG who together with FEET (Freshwater Environment ecology Trust ) are the main stakeholder groups furthering various aims and conservation of the reserve

Mothing


Weather  Dry 14 o C  70 % Humidity Dry 30th August 2014  10:00am -  1:15 am  Newt Corner

Mothing began early however one of the main problems with running traps is the main waves of Moths come in from about 10.00 pm onward and therefore dont lend well to open events due the lateness of such events

It is hoped that future event might involve morning sessions where the nights catch may be reviewed and  also more hands on engagement for youngsters via Wine Roping and Sugaring !!

Here are some of the finds that followed throughout the evening . Some early visitors to the trap included a Birch Shieldbug and a number of Caddis flies associated with the nearby water , these can be identified with difficulty but are often easier done from the ornate stone larval cocoons made from fine stone and grit. By far the commonest moth of the evening was the Large Yellow Underwing which arrived in numbers 12 early in the evening . An aproxmate total of 25 species where recorded

Recent Good Conservation Input...

Well Done to all those who particpated i recent practical work and engaged in recent measures to improve the reserve in order to protect areas from over use whilst it may seem a big reserve it has come under  more  pressure from increased use . The measure shown will help protect a small area of conservation value.

Thanks to Countryside Services and Volunteers measures like this will keep important features that make Cromwell Bottom a unique place . Sensitive cutting of the meadow to produce a Mosaic Habitat and keeping floristic stands along the Green Corridors and pathways help keep our hedgerows living and healthy and keep the diversity of flora and fauna at Cromwell in a healthy state and what it should be on the Tin a Nature Reserve  -  so a very well done on this project

On a slightly different note I am pleased to report a find of Broad leaved Helleborine Elsewhere on the reserve

Thanks to Chris Brooks

The Sisyridae, commonly known as spongeflies or spongillaflies, They're active at night or twilight and are tiny, with a wingspan of 1 cm (0.4 in) across at most and sometimes less than half that. Their minute form retains the complicated, lacy wings and giant, sparkling eyes common among Net-winged Insects.Adult spongillaflies are crepuscular (Active at Twilight)  or nocturnal. They are omnivores, sometimes hunting small invertebrates, but mainly scavenging on such animals' carcasses, as well as on pollen and honeydew.
