Crickets in December
I can hear no crickets tonight. But a few nights ago I was coming back from holiday shopping and heard them as I was walking home. Crickets in December! Will they come back this year?
The gulf fritillaries are still active. I have eggs and caterpillars in the house, and I saw the out gallivanting in the yard today. Usally they are around all year.

Well, the rains have paused and the crickets were back last night. I wonder how long they will last. The sound of crickets is familiar to most of us, but what about the sound of a courting medfly. For some interesting insect noises, try this link:

crickets
I think of cricket songs as a summer event. But I have been noticing the last few years that they are definitely still singing in the fall. In fact, they were singing just a few days ago. But now that the rains have come, the songs are gone. It is sad, but we really need the rain, so i am welcoming fall.

Bot Garden Insects
A couple of days ago, I was in the UC Botanical Garden to attend to my docent duties. The kids were fourth graders who had come to the Garden to learn about how Indians used plants. I did my best to inform them. Here they are before the tour listening to the head docent.
After the tour I took some pics of insects in the Saint Catherine's Lace,

Butterfly Class
Yesterday, my Albany Adult School butterfly class met at the Tilden Botanical Garden to go for a walk. It was cool and overcast, so we didn't see many butteflies, but the ones we did see sat around long enough so that we could get a good look at them and identify them. There was a field crescent trying to camouflage itself on an orange sign and a woodland skipper on the path, also well camouflaged. We enjoyed being out amoung the plants and maveled about how many were in bloom in September. We will meet one more time in the classroom and go for one more walk. Hopefully it will be sunny next week.

Butterfly Presentation
Yesterday, Andy and I did a presentation at MIG, a landscape architecture firm in Berkeley. It was the first time ever that Andy had put together a powerpoint presentation, and I must say it turned out rather well. Very nice pictures of butterflies. And he brought in plants to show what the caterpillars like to eat. He put a lot of work into his presentation.
On the other hand, I was lazy. I just put the monarch lifecycle in the DVD player, and played it. I didn't even narrate like I usually do. The audience seemed to really appreciate the presentation, and some stayed afterwards asking questions.
It is a busy week. Tuesday was my class at Albany Adult School, and Friday I am supposed to give presentations at LeConte. We have to take advantage of summer while it is still warm and sunny.

Dead
That sad looking caterpillar is a dead pipevine swallowtail. I don't know why it died, but I suspect that the Aristolochia manchuriensis that it was feeding on is just too toxic. The butterflies seem to prefer to lay eggs on it, and the caterpillars become so dense on the leaves that they sometimes completely defoliate the vine. But they don't seem to survive very well. Even some of the larvae that I brought inside and fed on Aristolochia californica died. But those that I collected from A. californica and raised on A californica did fine. So I wonder what is going on here. Maybe I will do a study next year.

Garden Show
On Saturday, Andy and I went to Strybing Arboretum in San Francisco. They had their annual garden show, and as usual, Andy and I were there doing butterfly education. There is Andy in his orange shirt, setting up the table full of lovely flowers. People love flowers. Butterflies like flowers, but I think people like them even more.
We had Sunday to rest (well not really, but no butterfly activities) and then we did a talk for Five Creeks at the Albany Community Center on Monday night. They were only expecting 20 people at most, but more than 40 came. They mobbed Andy, as can be seen in the second picture. They just couldn't get enough of his beautiful displays. Thank goodness for tech geeks. I couldn't get the computer to show the monarch lifecycle, but someone in the audience got it going. I would have been lost without it. This was the most enthusiastic audience I have ever spoken too. They loved the film, and they loved Andy's beautiful displays. They asked many questions, most of which I could answer. I talked a lot about weeds, and even though the group probably prefers natives, they enjoyed hearing about what the butterflies prefer. We had a great time!

I'm Famous!
Well maybe not famous, but as a result of the interview Andy and I did with the journalism students, I was mentioned in an Examiner article by John Curley: http://www.examiner.com/x-366-SF-Photo-Examiner~y2008m6d16-In-the-garden?comments=true
It is about the controversy over weeds and it includes a link to the UC Botanical Garden and to my movie, In the Company of Wild Butterflies. It is nice to get the exposure. And it is nice having someone help me in trying to educate people about weeds.

Raking and Mulching
In a normal garden, people rake up the old dead leaves and put down mulch to discourage weeds from growing. In a butterfly garden, this is not the best approach. Check out the pics. The green chrysalis on the nasturtium leaf is a cabbage white. The brown chrysalis on the dead mallow leaf is a lycenid. Although some caterpillars prefer to pupate on some kind of structure, like under a porch or on a fencepost, some like those in the photos, prefer the leaf litter underneath plants. Raking and mulching makes life difficult or impossible for these butterflies. It also ruins the habitat for many of our native bees which nest in the ground. So although the humans prefer a tidy garden, the insects want a wilder environment. If you can't entirely give up these normal gardening practices, at least try to leave a part of your garden au naturale to give the tiny animals a chance.

Box Elder Bug
To most people, any small crawly thing is a bug. A fly is a bug, a centipede is a bug, even an earthworm is a bug. But to an entomologist, only something in the order hemiptera is called a bug. The box elder bug is a true bug, and you can tell because of the v-shape on its back. "Hemiptera" means half-wing, and the V marks the wing where it changes from hard to membranous. Stink bugs are also true bugs.
February is always spring in Berkeley, as evidenced by the activity of the insect and plants. The cabbage whites are flying, the birds are singing, and so many things are in bloom: manzanitas, acacias, daphne, oxalis, and on and on. We had our rain in January, so Feburary is a time to enjoy all the flowers that result.
