Phytoliriomyza variegata (Meigen, 1830)
< back | next >
an initial gallery develops into a blotch

 

Food Plant: Colutea arborescens (Bladder-senna) and Astragalus glycyphyllos (Wild Liquorice)

Mine: June, August

Notes: Not yet a British species. Forms a narrow linear mine by the margin of the leaf which later develops into a blotch (as shown). The blotch has clumps of greenish frass. This mine is the first time that it has been seen on Astragalus in the UK, but needs breeding to confirm this species.

Data: 23.vii.2010, Kettering, Northamptonshire, VC 32
