Gardening in Harmony with Nature, Part 3

The Flickers have now left my oak woodlands and moved to higher elevations in the Coast Ranges; I’ll look forward to seeing them again when we’re camping in the forests this summer. Meanwhile, the Tree Swallows are here already and I’m waiting to hear the first calls of the Ash-throated Flycatchers as they arrive from wintering grounds in Baja California. For the last five or six years they have shown up about the fifth of May, and by June are raising a brood in the nesting box hung in an old Coast Live Oak.

More on Lycaenidae

Several other smaller groups of butterflies are included in the larger family commonly known as the Gossamer-winged butterflies; there are the Blues, the Coppers, Metalmarks and Hairstreaks. Most of these small butterflies are uncommon in Marin gardens; many of them have associations with just one or two species of native plants in specific habitats. There is just one butterfly within the sub-family of Hairstreaks that is often seen in Marin gardens, and that’s the Common, or Gray Hairstreak.

Acmon Blues

Acmon Blue – Plebejus (Icaricia) acmon

This little butterfly is fairly common, and more widespread than some of the other ‘Gossamer Wings’ (Lycaenidae); the Acmon Blue has a much longer flight period than many other ‘blues’ and it visits gardens, and can be seen in open fields, and even along roadsides.

On Gossamer Wings

The Lycaenidae; Blues, Hairstreaks, Coppers, and Metalmarks, are usually small, very delicate looking butterflies; many of them brilliantly colored and some with very interesting life cycles. The apparent fragility of these tiny creatures earned the family the common name ‘gossamer-winged’; but the vigor apparent in their life strategies, belies this moniker. This is the largest family of butterflies, with almost 6,000 species worldwide; but named species are often termed ‘complexes’ because there is still so much to be learned about their anatomy and behaviors.

Cabbage White

This lovely little Cabbage White butterfly (Pieris rapae) really stands out against the beautiful flowers of the 'Santa Cruz' Oregano.  It might seem unsafe, for a small creature, to be so visible in a habitat garden full of other creatures; but the white color sends a warning to visual predators.
