A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

First post-Victorian Depressaria sordidatella

The stand-out highlight on 27th July was what some people might pass off as a boring non-descript brown moth, but it was its general lack of features that made me wonder what it might be.  Obviously a Depressaria species but not looking much like any I am very familiar with.  A bit like one or two species I've seen once or twice, but not a convincing match for any of them.  I keyed it out using the key in MOGBI and that came out as Depressaria sordidatella.  That would be great, it being a species that hasn't been recorded in Norfolk since 1874, but keying these things isn't entirely reliable so I dissected it for confirmation.  The male genitalia of Depressaria sordidatella are rather similar to those of pulcherrimella (which also hasn't been seen in Norfolk since the 19th century) and douglasella (which I found the second county record of last year), and this moth's genitalia were clearly of this type - so straight away it had to be something good.  It took me a while to work out what the differences were, as they aren't described in any of my references - I'm left to deduce them from the various images of the genitalia.  In the end I think I worked out what the differences are, and that led me in conjunction with the external characteristics to confirm this one as Chervil Flat-body Depressaria sordidatella, apparently the first modern record in Norfolk.
