We had a walk along the canal from Luddenden Foot towards Brearley this afternoon.
Several young Alders were growing out of the canal bank by the towpath
and we found these small beetles and, we assume, their larvae.
Lots of damage to the fresh leaves though we failed to find any on the mature alders.
All in all there were maybe 30+ beetles but we only found 2 larvae.
With apologies for the small images. Click on the photos to enlarge.
We think they must be Alder Leaf Beetles – Agelastica alni
Also one from yesterday on the garage door – think it must be the species as described below ?
Hawthorn Shieldbug – Acanthosoma haemorrhoidale
