Orange-tip Butterfly – as a follow-up to an earlier post on these lovely, and quite common, butterflies here is a drawing I did a while ago about their life-cycle as it is worth looking out for their distinctive chrysalis at this time of year. Orange-tips lay their eggs singly (because the caterpillars are cannibalistic!) on the stems of plants like Ladies Smock, Jack-by-the-hedge (Garlic Mustard) and, in gardens, Honesty, (though
young survive less well on this). The eggs turn orange as they develop and the caterpillars, starting out orange, turn blue-green as they mature (see photo). By the late stage of the chrysalis the orange tips of the male can be seen through the increasingly transparent casing. Conditions: Warm and many dry days. Temperature: Max 17 Min 9C.
