Sher Falls sends this photograph of a Margined White nectaring on Erythronium revolutum at Honeymoon Bay, Lake Cowichan, April 22.   Jeremy Tatum writes:  This is a particularly heavily-veined example.  Many of the ones that we see in the summer at Cowichan Station are almost unmarked white.  I think the more heavily-veined ones, like this one, are spring-generation females.
