The Hover Fly
Syrphidae spp.
Bee mimic, not a bee. The most underappreciated pollinator in the garden. Works open umbels and composite heads that bees often overlook.
The Planters' Guild · A Pillar of the Guild
The creatures that close the loop. A field guide to twelve Bay Area pollinators paired with the flowers their bodies fit, biweekly from Late 2026.
Most pollinator writing starts with the bee. Honey, bumble, sometimes the cultural anchor that everyone already knows. We start with the relationship.
A long-tubed flower exists because something with a long tongue lives nearby. A flat composite head exists because short-tongued flies and small bees needed a landing pad. Read the pollinators and you read the garden.
The Pollinator Library covers twelve Bay Area pollinators biweekly across Late 2026 and into Spring 2027. Each entry takes one creature, pairs it to the flowers its body fits, and teaches you to recognize both the pollinator in flight and the floral architecture that needs it. The shelf below is arranged in reading order, № 01 to № 12 — from short-tongued generalists through specialist long-tongues to the only vertebrate on the shelf, Anna's hummingbird.
The Hover Fly
Syrphidae spp.
Bee mimic, not a bee. The most underappreciated pollinator in the garden. Works open umbels and composite heads that bees often overlook.
The Sweat Bee
Halictidae spp.
Tiny, often metallic green. Ground-nesting solitary bee. If you've seen a small flying jewel on a daisy, this was probably it.
The Honey Bee
Apis mellifera
The cultural anchor. Non-native, but the baseline most readers already know. We start here, then move outward.
The Mason Bee
Osmia lignaria
The orchard's first pollinator. Solitary, early-spring, faster on fruit blossoms than honey bees in cold weather.
The Leafcutter Bee
Megachile spp.
The bee responsible for the perfectly circular notches in your rose leaves. Distinctive nest behavior, important native generalist.
The Bumble Bee
Bombus vosnesenskii & spp.
The primary Bay Area buzz-pollinator. Sonicates flower anthers to shake pollen loose. The reason your tomatoes, blueberries, and eggplants set fruit.
The Carpenter Bee
Xylocopa spp.
The biggest native bee. Will chew through corolla bases to nectar-thieve when flowers are deeper than her reach. An ecological side door.
The Painted Lady
Vanessa cardui
The Bay Area's mass-migration butterfly. Generalist nectar feeder, larval host on thistles and mallows. A common doorway into butterfly identification.
The Anise Swallowtail
Papilio zelicaon
California native. Caterpillar host on fennel, parsley, citrus. The argument for host plant versus nectar plant lives here.
The Monarch
Danaus plexippus
Milkweed obligate. Carries pollen in unique sticky packets called pollinia, the same mechanism orchids use. A cultural and ecological anchor.
The White-Lined Sphinx Moth
Hyles lineata
Hovers like a hummingbird at dusk. Tongue reaches deeper than almost any other Bay Area pollinator. The reason night-blooming flowers exist.
Anna's Hummingbird
Calypte anna
The only vertebrate in the Library. Year-round Bay Area resident. Red tubular flowers like California fuchsia, currants, and monkeyflower exist because she does.
Bookmark the page or follow The Window Box newsletter to know when entries begin. Scanning to identify a pollinator you spotted? Work the visual: small short-tongued flies and bees on flat composite flowers up top; long-tongued butterflies and the hummingbird on tubular flowers near the bottom of the shelf. The morphological ordering predicts what flowers each creature prefers — the editorial argument the pillar will spend twelve entries making.
