Mines createated by members of the Helizelidae family are as rare as hen's teeth in Calderdale if my attempts to find them are anything to go by, so to find evidence of two species in three weeks was pretty special.

6.001 Shining Dogwood Cutter (Antispila metallella), mine and cut-out on Dogwood at Salterhebble on Aug. 18th.
This cut-out had a strange construction inside which I initially thought may have been the work of a parasitic wasp larva. It appears however to be the egg of a lacewing, they create this stem and lay on top of it to deter predators.

A line of frass can just be made out along the mid-rib, then along a side vein where it then crosses the leaf blade into another vein and then back towards the mid-rib. The larva perished before reaching the cutting stage
