I am a highschool student in Arcadia, Southern California, and I live pretty close to the sierra madre mountains (in the north) where supposedly a bunch of ceanothus grows. If anybody has any experience on this subject, is it possible for me to began searching for them around this time of year in those mountain ranges? And if possible, are there any other possible sites in which I can find Euryalus in southern California?
I would really love to know if anyone has found any sites in these areas where Euryalus (larvae, eggs, cocoons or adults) could be found in these general area.
Besides that, If anyone is breeding H. Euryalus and H. Cecropia at the same time this upcoming summer/spring and has a surplus of both sp. of cocoons, I would love to purchase some of each!
Thank you for your time!
Regards,
Jason Ni

下午好，
You could try searching for cocoons but I would suggest taking a beating sheet later when there are larvae present. Usually it can be easier to find larvae by searching for any frass on the beating sheet as sometimes you can shake off frass stick on the host making it easier to narrow down larvae.
I didn’t know you were in high school! Aren’t you 21?

I live in Northern California and found Hyalophora Euryalus in Sonoma County (Occidental)as an adult/rare visitor at lights.The larvae however, were found more frequently on Ceanothus in the month of July in their later instars/ close to fully grown.It took a fair amount of searching to find them however and about half were parasitized by some type of wasp. I think if you closely search areas of healthy stands of Ceanothus you stand a good chance of finding larvae.I have heard that the H.Euralus "flight season" can occur as early as February in Southern Cal. and you may be successful at finding H.Euryalus larvae earlier than we do up here in the north end of the state(perhaps in May or June)and folks with more knowledge than myself will know if this species is double brooded in your area.Regardless,it takes a bit of searching to find even one larvae and I found that they are found higher up on the Ceanothus.Last week I found a huge H.Eurylus cocoon on a dead Ceanothus shrub in Lake county, but as Usual, a rodent or bird had gained access and made a meal of it! Good Luck! It will be Interesting to hear how your search goes!

I was able to collect 5 specimens of male H. euryalus with a mercury vapor/black light set up last April in Silverado Canyon in the Cleveland National Forest in Orange County. The dates were 24 and 26 April. They all came in just after midnight. I don't know if that is a common spot for them or if I just got lucky, but hopefully that provides one good data point.

Yeah I do generally think it might be easier to search for larvae especially at this time of year. But can you please explain what a beating sheet is? |

I haven’t got any good information from browsing the web so far besides a few sighting spots on butterfliesandmoths.org, I’ll be sure to try to scout for some healthy ceanothus strands whether today or during my spring break! |

I do remember seeing some historical records of them being found there, but I haven’t tried or made a mercury vapor light before. I’ll see if I can give it shot during the summer. |

A beating sheet is a cloth or something preferably white used to collect insects. Google it and a picture will give you a good idea of what it is. |

Regards, Jason Ni I don’t have much knowledge as to the locality of H. euryalus, but I know that sagebrushbutterflies.com will start stocking cocoons in November. You should check them out. |
