Orange County Butterfly Sightings

Great Purple Hairstreak
Great Purple Hairstreak
Butterfly Sightings: Bob Gorman reported Great Purple Hairstreaks in South Orange County!
This butterfly is not often observed Orange County and is much more common in the desert
Orange Sulphurs
Orange Sulphurs were also reported and seen in South Orange County and up along the coast through Corona Del Mar. last year. This butterfly normally is mainly found at semitropical and tropical latitudes. It has been established in the Coachella Valley for over a decade. May have to thank global warming for its occurrence and push northward into Southern California.
Senna Sulphurs at one time were also uncommon sightings in the 1970’s - now they are common residents.
Bugs & Butterflies - June 2, 2013 - Thomas Riley Wilderness Park

I want to share with everyone how our day was as exhibitors at the Thomas F. Riley Wilderness Park “Bugs and Butterflies” event on June 2, 2013.

We are just guessing, but we think we talked to at least 150 people – well it seemed like it was that many! Glad to see so many parents bring their children to an event of this nature. These kids are our future scientists so they are an important audience!

We were able to not only enlighten the visitors about our OC NABA chapter with our new flyers, (Thank you Matthew!), we also had flyers for the Environmental Nature Center and talked up their Butterfly House. I was surprised at how many locals did not know of its existence! A wonderful place to visit for tourist and locals alike!

We were able to share with everyone how inexpensive it is to join NABA – and I showed them samples of the two magazines they would receive each year as a member.  I'm sure NABA will be getting a few new members from Orange County very soon!!!

See you again next year at the annual Bugs and Butterflies Event!

Butterfly Sightings in Orange County

Orange County Butterfly Sightings and News:
Senna (Cloudless) Sulphurs and Cabbage Whites continued to fly into December and
even January as observed on warm sunny days in Lakewood, California, along with an occasional Monarch. Several Gulf
Frittilaries were also observed in this area especially around Passion Vine, its larva host and a butterfly which seems to fly
nearly year-around. Most of our swallowtail species had finished their final flights by early November. Three Echo (Spring
Azures) Blues and a Common Gray Hairstreak were observed hilltopping on Sugarloaf Peak at an Elevation of 3227’ off the
San Juan Trail in the Santa Ana Mountains on Jan 2, 2012 on a very warm day which is early for these species.
