Hemaris thysbe, the Hummingbird Clearwing Moth or Common Clearwing (wingspan 38-50 mm), readily visits flowers by day throughout the eastern half of the U.S. and Canada, where it ranges far to the north, even into the Yukon. Ken Philip reports them in Alaska: Interior Alaska: Fairbanks vicinity; Southcentral Alaska: Index Lake.
It is not difficult to see why many gardeners would mistake an Hemaris thysbe moth for a small hummingbird as it hovers, sipping nectar from flowers through a long feeding tube.
The moth hovers briefly, sipping for only a few seconds before darting off to a new flower. Green body "fur" and burgundy wing scales suggest a small ruby throated hummingbird.
Adults can be quite variable. See Vernon Brou images of two males followed by a female at bottom of page.
In New Jersey there are at least two broods of this hawkmoth and in Louisiana there are six broods at thirty day intervals with the first brood peaking at the end of March.

Note the pale area below the wing junctures (right side above) and the irregular edge of the burgundy-brown outer margin (left forewing above) as it projects (mid wing) into the clear area of the forewing.
H. gracilis is a similar species that has dark bars below the wing junctures and has a smooth curve to the burgundy-brown outer margin as it meets the clear area of the forewing.

Regular sized moths emerge from seemingly small pupae when this species is reared in captivity.
Larvae pupate in thin walled cocoons under leaf litter. Scan to right shows cocoon formed under a paper towel.
In that clump of flowers that was about 3 m square, there were 8 Hemaris thysbe and 3 Hemaris diffinis feeding at the same time. I really lucked out when one of each start to nectar on the same flower. That was my best shot."

Sam Jaffe has corrected the id to Hemaris thysbe.
Hemaris thysbe larvae feed on viburnum and related plants and the clearwing adults captured with a butterfly net on June 1, were put in a sleeve over growing viburnum.
The sleeves I use are made out of a very light weight material called Remay cloth. The cloth is intended as a spring garden cover. The sleeve is more like a sock, six feet long with a six foot circumference. I pull it over a few branches of viburnum and then insert the captured moths.
Pale green eggs were deposited singly on the undersides of foliage and small larvae remained well camouflaged, resting on the ventral mid-leaf vein.
A second instar larva is depicted above and to the right.
This lateral view of a second instar hornworm larva reveals the faint orangy-red spiracular circles and relatively large head and well developed anal horn.
Larvae remain well camouflaged in rearing sleeves, and, in the early instars, only the constant rain of small droppings assures their presence.
The larva to the right is approximately 3/4 inch long.
On July 9, I took several fifth instar larvae from the sleeve. One is depicted to the right. The anal horn is now blue and body bulk makes head of a more reasonable proportion.
Just a few days later, the top half of the larvae turned purple and they began to leave foliage in preparation for pupation. I placed them in a paper sandwich bag under some loose paper towelling and then placed the entire bag in a dark bucket.
Tom Murray, David Wagner and Jim Tuttle all indicate there is also an orangey-pink prepupal form, and the lateral line runs from S1 to the horn.

Pupae are deceptively small, dark brown, and smooth-skinned.
These three were removed from thin walled cocoons spunup under paper towelling. They will be stored between layers of tissue in ziploc containers placed in a mini fridge.

In response to a question about nectar sources for Hemaris species, I have copied the following from Insectnet.com:
Here in Upstate New York, they are daily visitors to my butterfly bushes (Buddleia). I've also seen them around the wild honeysuckle, which is listed as a host plant for the larvae. (Kevin)
In Tulare, California, they come to Star Jasmine, Honeysuckle, Zauschneria, Gaura, and Evening Primrose. In fact my Mexican Evening Primrose have larvae on them. I'm assuming they're White-lined Sphinx. (Dennis).
Hemaris spp. come to mint, dogwood, purple cone flower, blackberry, trumpet vine, and various species of milkweed, amongst others in Illinois and elsewhere. (Jeff Prill).
I have seen them at blackberry blossoms and butterfly weed on Prince Edward Island in eastern Canada. A recent planting of French lilacs has also been attracting these moths.
In New Jersey I have seen them butterfly bush, joe-pie weed, lilac, honeysuckle. (Bill Oehlke)
Sandy Westermann reports the adults nectaring at bee balm (Monarda).
Kathy Johnstone, Branchport, New York, indicates these moths have a strong preference for the monarda and phlox in her garden. Rebekah Garris reports them on Spotted Knapweed in Sussex County, New Jersey.
Nicole Kovacs of Delaware writes, "We have almost daily visits to our deck planters by a clearwing hummingbird moth. The first sighting was in June, and still in July we are still seeing it. The first visit was on a red petunia hanging basket. But now in bloom are the yellow lantana to which it has been showing a preference."
Those who first published descriptions and
assigned scientific names to many insects, simply chose names of
biblical or mythological origin without any real descriptive
qualities. Their purpose was simply to set a standard for purposes
of identification by assigned name. On some occasions, names,
mostly of Latin or Greek origin, were chosen to signify a particular
character of the genus or of an individual species.
The genus name "Hemaris" is probably a Latin adjective form for
blood. It may have been chosen by Dalman based on the burgundy-red
scales on the wings.
"Thysbe" may have been taken from Shakespeare's
A Midsummer Night's Dream
or from the more original source, Ovid's Metamorphoses (Thisbe).

The pronunciation of scientific names is
troublesome for many. The "suggestion" at the top of the page is
merely a suggestion. It is based on commonly
accepted English pronunciation of Greek names and/or some
fairly well accepted "rules" for latinized scientific names.
The suggested pronunciations, on this page and on other pages,
are primarily put forward to assist those who hear with internal
ears as they read.
There are many collectors from different countries whose
intonations and accents would be different.
