Monochroa tenebrella in daytime

Here's another diurnal target, a bit like Adela fibulella and the Micropterix spp but harder to find.  Like them it's rather metallic and rather small.

Monochroa tenebrella is a Gelechid, so holds its pointy-tipped wings relatively flat.  It's about twice the size of a Micropterix.  There are no wing markings: the whole moth is shiny metallic browny-green.  The only distinctive feature is the white antenna tip of the female.  There are only a few Carms records, but I found a thriving colony on Sorrel in our garden and also swept one from a lane bank in the far west of the county today.  The two in the photo were scampering, jumping and fluttering around a stunted Sorrel plant at 11:30am in an open, parched bit of short grass, along with 10+ of their friends in a bit of a frenzy: I suspect they were males gathering at a female.  It's probably worth sweeping any bit of rather dry Sorrel-rich (or Sheep's Sorrel-rich) grassland, or just looking carefully around Sorrel plants while you're out searching for Foresters.


  1. I saw this species, for the first time, in Caernarfonshire last week. No doubt massively under-recorded!

  2. A really useful, instructive blog again, Sam.
