Caerau C.O.P (Caerau Old Pit) area

Sunny and Warm with new blossoms for the year in Bastard Cabbage, Midland Hawthorn, Southern Marsh and Early Purple Orchid, Common Mouse-ear, Common Sorrel and Square Stalked Willowherb.

Few butterflies about including Orange-tip and Dingy Skipper. The latter formerly a rarity in the valley now seems to be everywhere I go with suitable habitat.

Day-flying moths well represented in Common Heath, Silver Ground Carpet, Brown Silver-line, Common Carpet, Micropteryx calthella, Crambus lathoniellus, Crambus perlella, Glyphipteryx simpliciella & thrasonella, Elachista argentella and the ever present Burnet Companion. Plus a few Coleophoras I didn't bother to check.

Hoverflies were numerous with 3 new for Caerau in Pipiza austriaca, Sericomyia lappona [no photo sadly] and Microdon myrmicae/mutablis.

Other insects include a bronze Reed Beetle which I thought would be easy to ID until I found out there were 21 species in the family. The Key suggests Plateumaris sericea, but I'll have to put it on Irecord for confirmation.

 Eristalis horticola
 Microdon myrmicae/mutablis. Can only be separated during larva stage. Although myrmicae lays in black ant species nests and mutablis lays in red ant species nests.
 Pipiza austriaca
 Syrphus ribesii
 Xylota segnis unusually visiting Broom flowers
 Common Heath
 Orange Tip - female

Reed beetle - probably Plateumaris sericae.

Birds were represented with singing Blackcap, Whitethroat, Tree Pipit, Willow Warbler, Chiffchaff, Siskin, Linnet, Stonechat, Meadow Pipit, Skylark, Goldfinch and 3prs Swift, 2prs House Martin and 2prs Swallow
