An observation

November 7, 2017

While watching wasps feeding on ivy nectar by the house recently a Silver Y moth came by to refuel.  Immediately, on its first approach to the flowers, the moth was grabbed in mid flight by a wasp and wrestled to the ground.  As can be seen from the photos below the moth is a good bit bigger than the wasp.

Within a few seconds the wasp had immobilised the moth with one or more stings and within just a minute or so it had dismembered the moth ready for removal to its nest.  The moth fought hard throughout the ordeal, the wasp becoming coated in fluff and scales shed from the moths body but, once immobilised with a sting from the wasp, there was no escape for the moth.

The wasp is the German Wasp Vespula germanica of which there have been huge numbers here this year.  I have seen hornets take other insect in mid flight but this is the first time I have seen one of the smaller wasps take such large prey.

Away Day to Ynys Hir RSPB Reserve

January 16, 2017

Our group visit to RSPB Ynys Hir Reserve yesterday was a great success.  Twelve members made the trip.  Despite rather persistent drizzle at times and poor long range visibility we gathered a good list of 57 bird species during the day.  Most of our time was spent in the hides.  Highlights on the reserve were a marsh harrier, two merlins together (and later two further sightings of single merlins), a common and a green sandpiper up close and the highlight of highlights a great grey shrike.

Moving on to Aberystwyth seafront in the late afternoon we watched the starling roost assemble, quite a sight.  Starling numbers soon built up and with them came a peregrine, making a successful kill.  On the beach were 10 turnstones and on the rocks a rock pipit and an adult Mediterranean gull.

We came home an excited bunch and hardly noticed the drizzle.

This winter is proving to be a Waxwing one – with birds moving in from Scandanavia in good numbers. Waxwings are stunning little birds with a shrill tinkling call. The north and east of the country has seen flocks up until Christmas when they seem to have finally trickled down into mid Wales. A group of 5 are currently feeding on berries in Llanwrthwl and 20+ are in Llandrindod by the old school. Its well worth looking out for them – they seem to eat any berry going , including non-native garden species. The Llanwrthwl birds like pink ash berries that the winter thrush species ignored in the Autumn for example.There must be some in Rhayader somewhere, so check out those berries and listen for the call.

Leaf-mining moths

November 8, 2016

The meeting of 21st October proved to be quite an eye-opener.  Many thanks go to Norman Lowe (Brecknock Moth Recorder) for such an interesting and inspiring morning.

Ten people took part in the search for evidence of moth leaf-miners  –  the evidence being the burrowing galleries and blotches on leaves left by their caterpillars.  With the aid of Norman, and his key to the more common species, twenty-two species were found during the morning.  Norman, keen to find more, stayed on into the afternoon and found a further eight.

Nearly all the thirty species found were new for the site despite many years of light-trapping there.  Clearly leaf mining moths don’t come to light very often, if at all.  All were common and widespread species but Norman went away happy in the knowledge that the  outcome filled a gap in what is known about the distribution of moths.  His hope is that the morning will also inspire others to go in search  –  and send him records of their findings.  Many can be identified from photographs.

Dinefwr away day

September 29, 2016

A great day was had at Dinefwr castle and park on Sunday last (25th Sept) –  shame there were not more of us.  The grounds and far reaching views from the castle ruins were absolutely stunning.  Among the huge ancient trees and shubberies we found blackcaps, chiffchaffs, goldcrests and tree creepers with other woodland birds.  On flowering ivy draping a wall were comma and red admiral butterflies and a goodly number of hornets. Around the Mill Pond was a kingfisher and common darter, migrant hawker and southern hawker dragonflies. Then to top it all, at the oxbows wetland we found our ‘bird of the day’  –  a great white egret stealthily wading the water edges.  The White Park cattle were up close and personal and in spectacular condition.  A few fallow deer snuck about the woodland edges and speckled wood butterflies fluttered by.  This potter in the park provided us with wildlife and historic interest wherever we went.  Dinefwr is a wonderful place to visit.  We must return next spring  –  to seek out those elusive lesser spotted woodpeckers.
