Sphinx kalmiae, the Laurel Sphinx (tongue length 40 mm), is found in the eastern third of North America from the maritime provinces to northern Florida. It ranges further to the west in Canada and has been confirmed in Saskatchewan. Georgia is the specimen type locality.The lower forewings are predominantly brownish-yellow with a fairly wide dark bar along the inner margin. At rest the wings hug the body, giving the moth a long slender look. Both males and females come to lights on Prince Edward Island, Canada.

FLIGHT TIMES:In Canada, Sphinx kalmiae is single-brooded with most adults on the wing in June and July. In New Jersey and Connecticut and states of that latitiude, the Laurel Sphinx is double-brooded (late May-June flight and then again in July-August). There are as many as six broods in Louisiana with the first brood appearing in early to mid April.Here on P.E.I. I tend to see kalmiae (mostly males) at lights in July and early August.

The specimen to the right is somewhat worn. |

Laurel Sphinx larvae feed primarily on lilac and fringe. This day old larva is well camouflaged on the underside main lilac leaf vein.Larvae have also been found on privet. Female Sphinx kalmiae don't seem to come to lights nearly as readily as males, but when captured they will readily oviposit inside a brown paper bag. |
The fourth instar larvae to the right (courtesy of Tim Dyson--August 7, 2005) now has some of the distinctive markings and colouration of kalmiae and can consume several lilac leaves in a 24 hour period, leaving just a centimeter or two of leaf stem.Rearing quarters should be cleaned regularly, and care should be taken to avoid excessive humidity. Note the "white leggings" above the "black boots" on the prolegs and the black tip on the green "horn". The fifth instar larva (below, courtesy of Tim Dyson) will leave foliage in a day or so and crawl around the bottom of the container, looking for soil in which to pupate. |
Fifth instar, note black on head, tail and on abdominal legs.
The anal horn is now blue with extensive black markinngs.
Possibly there was some laurel or fringe in the undergrowth.

Visit Sphinx kalmiae, adult, Ozaukee County, Wisconsin, June 6, 2008, Kate Redmond I pick up such Sphingidae larvae with my fingers and gently put them in a bucket, bottom-lined with several layers of loose, dry paper towels. The larvae will crawl under the towelling and pupate on the bottom of the bucket.

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.
The Sphinx sat on a high rock by a road near Thebes and posed a
riddle to all who wished to pass. The Sphinx strangled all who
could not answer its riddle.
"The name "Sphinx" derives from the Greek word
"sphingo," to strangle, or "sphingein," to bind tight, based on
the Sphinx's habit of strangling its victims. The name was
subsequently applied to the Egyptian and other arabic sphinxes
because of their physical similarity to descriptions of the mythical
Greek Sphinx."
Sphingidae larvae often strike a pose similar to that ascribed to
the "Sphinx", so possibly that has to do with the choice of the
genus name.
The species name "kalmiae" probably
originates from Pehr Kalm, an 18th century Swedish naturalist.
"Kalmia" is the genus name for various laurels. Moths may have
been seen nectaring at the flowers, or the golden colour of
the forewings might have suggested the "laurel wreathe" used to honour
"gold medalists".
