The elusive butterfly. Not the easiest things to get a snap of but I've been seeing plenty of butterflies on recent rambles in Hertfordshire. Is this blur a Brimstone? Seen here making its way around a patch of Henbit Deadnettle.  

 A Marbled White. Thistles are among their main food plants.

Skipper on a Vetch. An Essex Skipper perhaps or is it a Small Skipper or a Large Skipper?

A Comma. This species declined alarmingly then made a comeback so it's not all bad news.

 Small Tortoiseshell on Wild Marjoram. A glimpse of both the colourful upper wing and the dusky underwing. Wild Marjoram is noted as a butterfly plant par excellence.

 Wild Marjoram again. And the butterfly... well, it's a White. Would it be a Large White? Note to self: brush up on butterfly ID skills.
