Hawkmoth

Sphingidae (family)

Also known as: Sphinx moth, Hawk moth, Hummingbird moth

Large, fast-flying moths in the family Sphingidae — among the most-charismatic and most-effective pollinators in temperate ecosystems. Named for their hawk-like flight (rapid, hovering, capable of flying backward). Many species are crepuscular or nocturnal, pollinating night-blooming white or pale flowers (moonflower, evening primrose, datura, many jasmine species, tobacco). Some, including the hummingbird clearwing, are diurnal and frequently mistaken for hummingbirds. Hawkmoths can have proboscises 2–8 inches long — long enough to access nectar deep in tubular flowers no other pollinator can reach.

Biology

Hawkmoths are among the largest moths in temperate regions — wingspans 2–6 inches, robust bodies, exceptionally fast flight. They:

Hover — stationary in flight while feeding from flowers, similar to hummingbirds
Fly backward — by rotating their wings, unlike most insects
Fly fast — sustained speeds of 12+ mph

Most temperate hawkmoth adults feed on flower nectar through a long, coilable proboscis. Larvae are large, often horned at the rear (“hornworms”), feeding on specific host plants — tomato hornworm (Manduca quinquemaculata), [[tobacco|tobacco]] hornworm (M. sexta), pandora sphinx (grapes and [[virginia-creeper|Virginia creeper]]), white-lined sphinx (many wildflowers).

The pollination niche

Hawkmoths fill an ecological role no other pollinator group can:

Long proboscises — 2–8 inches, capable of reaching nectar at the base of long-tubed flowers
Night-blooming flower specialists — most temperate hawkmoths are crepuscular or nocturnal; they pollinate white or pale-colored, heavily-scented night-bloomers
Long-distance flight — daily ranges can exceed 10 miles; they connect populations of host plants across landscapes that other pollinators can’t bridge

Plants pollinated primarily by hawkmoths include moonflower, datura, evening [[primrose|primrose]], four-o’clock, many night-blooming jasmines, [[tobacco|tobacco]], petunia (wild), nicotiana, and Madagascar’s Angraecum sesquipedale — the orchid Darwin predicted (correctly) must be pollinated by a moth with a 30 cm proboscis.

The hummingbird-moth confusion

Some hawkmoths are diurnal and look strikingly like hummingbirds:

Hummingbird clearwing (Hemaris thysbe) — small, fuzzy, with transparent wings; commonly mistaken for hummingbirds
Snowberry clearwing (Hemaris diffinis) — similar; black and yellow

These diurnal hawkmoths visit phlox, [[wild-bergamot|bee balm]], lilac, butterfly bush, and many garden flowers in the same hovering, nectar-seeking way as their nocturnal cousins.

How to host hawkmoths

Plant night-blooming flowers for the nocturnal species — moonflower, datura, four-o’clock, evening [[primrose|primrose]], flowering [[tobacco|tobacco]]
Plant tubular flowers for hovering specialists — phlox, [[wild-bergamot|bee balm]], salvia, mountain mint, butterfly bush
Tolerate hornworms on tomatoes — the moths are pollinators; the caterpillars are short-term feeders
Leave outdoor lighting off at night — light pollution disrupts nocturnal pollinator behavior significantly
