Gulf Fritillaries Are Back!

Mar 28, 2016

Okay, where are they?

Shouldn't they be emerging soon?

They're in Davis and Suisun. Why not Vacaville?

We've been waiting--not so patiently after this long winter--for the reappearance of the showy Gulf Fritillary butterfly (Agraulis vanillae) on our passionflower vine (Passiflora).

On Saturday, March 26 (Easter weekend), a solo female fluttered into our yard and headed straight for the Passiflora. Not only did she reward us with our presence, but she laid several eggs, singly, on the leaves and tendrils.  They're the size of a pinhead and look like pure gold. That's because they are.

Spring is a time of renewal, rejuvenation and rejoicing.

Butterfly guru Art Shapiro, distinguished professor of evolution and ecology at UC Davis who has monitored butterfly populations in Central California for more than four decades, saw his first Gulf Frit of the year on March 16 in Suisun. Read what he says about these brightly colored orange butterflies on his website.

Butterfly expert Greg Kareofelas, an associate at the Bohart Museum of Entomology, UC Davis, rescued a Gulf Frit larva from his Davis yard last winter and on March 17 watched the adult eclose from its chrysalis. Lately he's been on Butterfly Alert. He's spotted a number of Gulf Frits in his yard, including a female on March 26. His count includes other species as well, including a monarch and Western tiger swallowtails.

No monarch sightings for us yet, but one mourning cloak, two Western tiger swallowtails and two pipevine swallowtails.

Saturday's appearance of Mrs. Gulf Frit, however, was special. It was a day before Easter. Instead of a visit from the Easter Bunny delivering hen eggs, this was a visit from a Gulf Fritillary who graced us with several bonafide eggs. Her own.
