Cheshire status: Formerly a widespread resident, but in recent years significant losses has meant that it is now only thinly distributed in very small numbers. At times during the 1970’s and 1980’s it was much commoner and its subsequent decline cannot easily be explained, although it is known that the Wall has always undergone periodic fluctuations. Normally double-brooded with peak numbers seen in late May and again in August, plus a partial third emergence in favourable years.
