Butterflies so far

Its been a slow stat compared to last Aprils record temps but at last there seem to be a few butterflies about.Comma,Speckled Wood ,Small Tortoiseshell,Peacock and Orange Tip have been seen this week at Cromwell Bottom and there have been a few reports of Brimstone from the Todmorden area.I am almost sure I saw a Green Hairstreak fly by at Ringstone this morning but I could not relocate it.
