   Andrew Simon writes:  Many of us are fond of the sweet, crisp taste of Evergreen huckleberries, which may be harvested, frost-covered, even as late as November.  Well, the Silver-spotted Tiger Moth is also fond of this plant, it turns out. Larvae of this moth depend on multiple host plants on the west coast, including conifers such as  Douglas-fir—but I have yet to find anything written regarding its taste for the leathery leaves of Vaccinium ovatum.

   Jeremy Tatum replies:  Yes, while Douglas Fir is the usual foodplant of this species, I have occasionally found the caterpillar on other plants, such as broad-leaved trees.  I haven’t kept a record of such plants, but the leathery leaves of Vaccinium ovatum certainly sounds like an interesting choice for this or any other caterpillar.
