Today while digging in the dirt in preparation for planting onions, we noticed this Anise Swallowtail Caterpillar munching on carrot greens.  Though we have grown carrots for ten years, and though Anise Swallowtails are relatively common in the area, this is our first sighting of a Caterpillar in the vegetable garden.

Julian Donahue confirms Cramer’s Sphinx indentification
It is indeed Erinnyis crameri, an infrequent stray to SoCal from farther south (once bred on Vinca in Riverside–see my more extensive comments on WTB?).
Nice find, Daniel. The specimen should go to LACM, or at least be reported to iNaturalist AND the BAMONA website <http://www.butterfliesandmoths.org/>, where the most recent Los Angeles County record is 1950!!

Cramer's Sphinx with good Depth of Field

Location:  Mount Washington, Los Angeles, California
Temperature:  54º F.  Light wind out of the North and low humidity.

So, we know that this is a Sphinx Moth in the genus
ErinnyasSphingidae of the Americas lists four members of the genus in California, and this is definitely NOT an Ello Sphinx.  The pattern on the forewings looks most like Cramer’s Sphinx, Erinnyis crameri, to us.  We have contacted Bill Oehlke to verify the species.  We worked really hard tonight, reshooting three times to first get a decent exposure and then to maximize depth of field.  We are quite proud of capturing this challenging image.
We can’t help but to wonder if El Niño might play a part in this sighting.

We couldn’t resist getting a ventral view of what we speculate is a female Cramer’s Sphinx.  We wonder if El Niño conditions are causing this typically Central and South American species to migrate North in an effort to expand their range in the event of global warming.

Bill Oehlke confirms ID
HI Daniel,
Yes, I am pretty sure it is crameri. Only other close one is oenotrus, but I favour crameri.
Thanks for thinking of me.
Bill

According to Sphingidae of the Americas “lacks black dots on the underside of abdomen” and even though the image is not the greatest, we still have the moth to inspect as it is still on the screen door at 6:42 AM.  There are no dots on the underside of the abdomen.  We would think that if this individual traveled a great distance, it would look more tattered than the individual that visited us, which looks more like a newly eclosed specimen.  There are only two postings on BugGuide, and one is from San Diego this September.

We got some better images.

Luckily it is cold out tonight, so the Sphinx did not mind that we rearranged its wings for some better images.  We have contacted Bill Oehlke and we eagerly await his input on the species.

When leaving the house today, we saw a large Sphinx Moth on the screen door, and at first we thought it was a Carolina Sphinx, but the markings on the wings were different and there were scalloped edges on the wings.  We determined on the Sphingidae of the Americas site that it is a member of the genus Ello, possibly a Cramer’s Sphinx.  We took some images with the old digital camera with a flash and a zoom lens, but alas, the camera must finally be failing as the card is not readable.  Undaunted, we pulled out a different camera, but the battery wasn’t charged and we managed to get one terribly underexposed image before the battery died.  The battery is charging and we hope to be able to get a better shot in an hour, and if luck is really with us, we can get an image in the morning by daylight.  The images on the corrupted card were taken with a flash, and we managed to move the upper wing to show the orange underwing with the black edge, and hopefully we will be able to duplicate that result when the battery charges.  This is the best we can offer at this time.

Erythrina Borer attracted to porch light

Upon walking out the front door this morning, we noticed this little Pyralid Moth that we recognized because of previous submissions.  There must be a coral tree nearby to have provided food for the caterpillars.

Just an update to the previous posting.  We believe the first Tiger Moth to arrive, the one on the lower left, is a female and we believe she released pheromones to attract a mate. Which will she choose??? In the past Painted Tiger Moths have laid eggs on the siding.  It seems we get several Painted Tiger Moths visiting each year, but we are still thrilled when we spot the first of the season.

Dear Sandy and Bettie,
Your large moth is a Black Witch.  Native to Central and South America, Black Witch Moths have been reported to migrate north during Mexican monsoons every fall, and they have been known to reach as far north as the northern border states and even into Canada.  Your individual is a female, as evidenced by the light diagonal markings across the wings.  Though they are frequently found in Los Angeles, a Black Witch sighting is always an exciting event.
