I have recorded Green shield bugs and Hawthorn shield bugs over the last twelve months, this one came as a surprise. It stayed only a short time unlike the others which can perch all day in one spot.
No interactions present.
There is a typo in the name (should be Elasmostethus interstinctus) so the other observations of the same species aren't showing up. Do you want to add another revision?
