Subject:  Spotted caterpillar from Ecuador

Your letter to the bugman:  I photographed this caterpillar (2-3 inches long) at the Jorupe Reserve on March 9.  The size and pattern of the eye-spots on the side look similar to those on some Eumorpha caterpillars, but I haven’t found a match to this.

Eumorpha Caterpillar

Dear David,
This is a beautiful Caterpillar, and because of its resemblance to the North American Achemon Sphinx Caterpillar and Pandorus Sphinx Caterpillar, we are quite confident it is also a member of the genus
Eumorpha.  Caterpillars of moths in the family Sphingidae are commonly called Hornworms because most members of the family have caudal horns.  Members of the genus Eumorpha frequently lose their caudal horns during the molting process.  We could not find any matching images on Sphingidae of the Americas, but many species on the site are lacking images of the caterpillars.  We will contact Bill Oehlke to see if he can provide a species identification.  We hope you will allow Bill to post your image to his site if he is able to assist.

Bill Oehlke Responds.
Daniel,
I sent image to Jean Haxaire and he indicates it is Eumorpha triangulum, but the plant it is on in the photo is not its natural host.
Bill
The larvae display several different colour morphs.

Ed. Note:  More information on Eumorpha triangulum can be found on Sphingidae of the Americas.

Excellent information.  Thanks very much.
(I have another one that I’ll send along shortly.)

Giant Silkmoth: Pseudodirphia menander

Dear H. Appels,
We are posting your image of a Giant Silkmoth,
Pseudodirphia menander, which appears to have recently emerged from the pupa and its wings have not yet fully expanded.  We located images of the moth on Discover Life, and there is also an image on BioLib.  Your other images are of a Cicada nymph and a Fishing Spider.

Spined Oak Borer

Dear Curious homeowner,
Do you have a fireplace or wood burning stove and do you store firewood inside the home?  This is a Spined Oak Borer,
Elaphidion mucronatum, which we identified on BugGuide, and according to BugGuide:  “Extremely polyphagous; hosts include most eastern hardwoods & shrubs.  Also noted in bald cypress (Taxodium distichum)” and “Eggs are laid beneath bark of dead hardwoods. Larvae feed beneath the bark for the first year and feed deeper the second year.”  Adults do not feed on wood.  We are presuming the individuals you found in your home emerged from wood you brought indoors.

Dear Tom,
This is a Hickory Borer.  Adult Hickory Borers visit blossoms where they feed on pollen, but larvae are wood borers.  According to BugGuide:  “larvae mine newly dead hickory, and sometimes other hardwoods.”

Honey Bee with full pollen sacs

Dear Bees,
Honey Bees are social insects that visit flowers to gather nectar which the bees store in the hive after converting the nectar to honey.  According to BugGuide, Honey Bees feed on:  “Nectar and pollen from flowers. Pollen is most important in feeding the larvae.”  While visiting blossoms, Honey Bees ingest nectar which is regurgitated upon return to the hive, and pollen is collected on pollen sacs on the hind legs.  The “big shoes” you describe are pollen sacs laden with pollen.  Here is an image from BugGuide of a Honey Bee laden with pollen.
