We have a spot of colour in this morning’s posting.  Aziza Cooper writes that on April 25, there were two Mourning Cloaks and one Cabbage White at Panama Flats, and one California Tortoiseshell at Mount Tolmie on the concrete reservoir at about 5 pm.  And Gordon Hart saw three Green Commas at his Highlands property.

St George’s Day

 

   Last year Ian Cooper found caterpillars of the Grey Hairstreak butterfly on the flowers of Mentha along the Galloping Goose Trail near Harriet Road.  Jeremy Tatum took one of them for rearing.  Photographs of the caterpillar are to be found on the Invert Alert posting for 2022 September 29, and of the pupa, 2022 October 5.  The adult butterfly emerged today, and was released by Jeremy and Ian where the caterpillar was found.  Below is a “studio” photograph of the underside by Jeremy.   After release, Ian managed to get photographs of the underside and upperside in a more natural setting, also shown below.
