    I spotted the white butterfly at work last week, is it a small white?


    And these birds at Slimbridge on Saturday but I wasn't sure if one was a reed warbler and one a chiff chaff.


    Thanks

    Hi Amanda.

    I think the Butterfly is a Green-Veined White (Pieris napi).
    The triangular black markings on the wing veins where they meet the edge of the wing are an identifying feature which is not present on the Small White.. Also you can just see the green colour on the underside of the nearer wing which gives it its name. This one is a "first generation" male as it has no black spots on the forewings. "First generation" means it has developed from a egg laid this spring which has developed into a caterpillar which has grown very rapidly. "First generation" examples will produce a second brood of adults ("Second generation") later in the summer whose larvae will turn into chrysalises to overwinter and then emerge as Butterflies next year.

    Whilst the Small and Large White's caterpillars attack cabbages and are therefore known to gardeners as "Cabbage Whites" the Green-Veined Whites prefer wild plants of the Brassica (cabbage) family and are not such a pest.



    Not sure about the birds I'm afraid as the lighting is a bit tricky to see the subtleties of the markings.

    Regards.

      I will bow to Peter's superior knowledge about the butterfly and agree with him that it is difficult to identify the birds. However, I don't think I can see a Reed Bunting there. I think the last two might be Willow Warblers as the legs look a bit to pale for Chiffchaffs but I could be wrong. It is much easier when you can hear them singing.

          Thanks Ron. They were very hard to isolate in the bushes. I think I saw a tweet (not from the birds!) that there were willow warblers around.

            Thanks Amanda.

            I have a "few shelves" of books which helps with the detail.

                I saw a tweet today that a Cetti's Warbler had been spotted at the Kingfisher Hide today, and I think that might be my mystery bird.
