Holtspur Bottom on Upper Thames Moth Blog

Tree-lichen Beauty moth Tree-lichen Beauty moth (Cryphia algae). Recorded at Holtspur Bottom in 2013 and 2014. A predominantly European species that has started to colonise the south of England. Flight season from mid July to August. Over-winters as a larva among lichens.


The Upper Thames Moth blog has occasional reports from our reserve at Holtspur Bottom.

Sunday, 28 September 2014: ... just short of 50 species. I'd hoped to tick off most of the Sallows on this visit but in the end the only one which turned up was Barred Sallow (in some numbers, including several of the smart dark orange form). Along with a handful of Light Emeralds, a single Small Emerald came to one of the lights as an unusual second brood. Pride of place, though, goes to the tiny and rather battered female Gem.

Thursday, 14 August 2014: Even though the moon was hidden behind clouds for almost all of the three hours that I was there, the combined effort of two MV lights brought in only 36 macro species and 30 micro species.  A couple of Plutella xylostella in each trap was the only suggestion of migrant activity...

Thursday, 24 July 2014: There were plenty of species flying (about 140 identified). Amongst the macros, Ruby Tiger and Flame Shoulder were particularly plentiful. Tree-lichen Beauty was added to the site list last August so it was good to see that species again. Amongst the micros the highlight Acompsia schmidtiellus. This marjoram feeder is quite an uncommon species and there are only about four previous records for Bucks.

Saturday, 5 July 2014: Highlights included Thiotricha subocellea, Myelois circumvoluta, Pempeliella dilutella, Dark Umber, Kent Black Arches, Obscure Wainscot, Waved Black and Dotted Fan-foot.

Friday, 13 June 2014: Just over 80 species were recorded. Of interest or new for the year were Mocha, Blotched Emerald, Barred Yellow, Fern, Privet Hawk-moth, Lime Hawk-moth, Maple Prominent, Purple Clay, Double Square-spot, Reddish Light Arches, Bordered Sallow and Uncertain.

Tuesday, 20 May 2014: Highlights included Mocha, Maple Prominent, and Campion...

Tuesday, 29 April 2014: Thirteen Cockchafers came to light, outnumbering any of the 30+ moth species caught! Light Brocade was nice to see there, but otherwise the only new-for-year sightings were micros (including Nematopogon swammerdamella, Pseudoswammerdamia combinella, Prays fraxinella, Cochylis atricapitana, Syndemis musculana, Dichrorampha acuminatana & Evergestis forficalis).

Sunday, 30 March 2014: Just over 180 moths of 23 species, of which the highlight was undoubtedly what seems to be the first ever March record for Scorched Carpet in Bucks.
