   Jeremy Tatum writes:  Jannaca Chick sends a photograph of a Catocala from Pedder Bay, September 5.   Our commonest Catocala here is C. aholibah,  though I can’t be completely certain that this isn’t the rather similar C. allusa, which also occurs here.  The caterpillars are distinct, with aholibah feeding on oak, and allusa  on willow.  I’ll be cautious, and label it Catocala aholibah/allusa.
