Black Mountains Micros


Monmouthshire's northernmost hectads - SO22 and SO23 - are woefully under-recorded for Micros.  SO22 had 49 recorded species and SO23 had just 4 (although only a small part of the hectad is in VC35).  After a day's work in Radnorshire I returned home via the Llanthony Valley, and stopped at three places to beat the hedges for Micros.  The first, near Capel-y-ffin, produced 13 species of Micro, all new for SO23 but all mundane.  The second, north of Llanthony, also held 14, with 12 new for SO22 and 4 Caryocolum blandella (new for Monmouthshire) disturbed from the hedge bank.  The third, in forestry south of Llanthony, produced 22 species including 8 additions for SO22; the distinctive orange Zelleria hepariella was pick of the bunch there.


There are still a lot of under-recorded hectads, especially towards the edges of the Vice-county, and diurnal micro recording can add a lot to these totals even if trapping is impractical.  Micro totals in two formats follow:

SO10 93 ST18 16
SO11 29 ST19 158
SO20 101 ST27 55
SO21 151 ST28 241
SO22 49 ST29 166
SO23 4 ST38 188
SO30 304 ST39 174
SO31 89 ST48 310
SO32 61 ST49 175
SO40 528 ST58 30
SO41 291 ST59 356
SO42 39
SO50 398
SO51 275
