Twelve Days of Christmas 2012

Since tomorrow is the twelfth day of Christmas, I thought I'd give you your belated gifts. Of course they're all part of L.A.'s surprising biodiversity, yes even those turtle wasps!

New Fly Species Likes to Party It Up Poolside in Brentwood

I've been scratching my head for a story to tell in this week's blog. At 6:20 last night it hit me! I've never related our Curator of Entomology, Brian Brown's, story of how he discovered a brand new species of fly, right here in Los Angeles! That's right folks, undiscovered fly species are here right under your noses oh and don't forget that one that  flew into your eyeball, maybe that was new to science too, I guess next time you should try to save it!

All kidding aside, there are likely hundreds of new species scientists have never discovered before, right here in L.A.. Brian is famous here at the Museum for saying, "It's just as likely to find a new species to science in L.A., as it is in Costa Rica [where he does a lot of his research], 100%."

All you have to do is look at the numbers. Scientists have described almost a million different species of insects. However, they estimate that there may be anywhere between 9 and 29...

Weevil is as Weevil Does: Total Agave Meltdown

I don't know about you, but I'm not freaking out about the end of the world on December 21. Though, I can tell you "who" should be those agave plants, that's who! So much so, that if I was magically turned into an agave plant tomorrow, I'd totally start partying it up in preparation for total meltdown. Seriously though, agave meltdown is no joke. It's a very real disease that is highly lethal to agave plants and we've just discovered it in the Museum's garden!

It all came about last week. Richard Hayden and Daniel Feldman, the Museum's garden staff, noticed that some of our Agave americana plants weren't looking so hot. Some plants had a few leaves that were wrinkled and beginning to discolor, others were so bad they weren't able to stand up straight anymore. Experimentally, Daniel tugged on a leaf of one of the sick agaves, and surprisingly the entire plant came out of the ground in his hand! What they discovered beneath the surface was not pretty. The...

A Plague of Grasshoppers on Figueroa?

Recently, our garden staff has been finding LOADS of grasshoppers, but what are they all doing here? Are grasshoppers good for our gardens, or are they destructive like the plague of locusts (a swarming variety of grasshoppers in the family Acrididae) that appear in the Bible?

 

On November 14, I snapped a decent picture of a grasshopper hanging out on a pitcher sage plant, Lepechinia fragrans. I thought I'd have a crack at identifying it, and hoped that, through the process, I'd be able to figure out what exactly they're doing in the garden.

 

Not a bad picture for my camera phone!

 

Armed with a trusty book, the Field Guide to Grasshoppers, Katydids, and Crickets of the United States, I began my quest. It was a long and arduous quest...

Thanksgiving for the Butter-butt (but not the Butterballs)!

Hold your horses...give me a moment to clarify this title, I'm talking about birds here! When I say "butter-butt" I'm actually referring to a small grey songbird that has a bright yellow patch on its derrière (yes, this really is what dorky birders like myself call this bird when we're out birding). In particular, I'm talking about the below pictured butter-butt, that narrowly escaped death hence the giving of thanks. In contrast, all those Butterball turkeys won't be giving much thanks. But hey, maybe you'll be inclined to give some on their behalf!
If this bird had a speech bubble, what would it be saying?

This is what Museum bird expert, Kimball Garrett, has to say about butter-butts, a.k.a. Yellow-rumped warblers:

Massive Black Fly aka Mexican Cactus Fly

Earlier this week I was outside being interviewed about Entomophagy, the practice of eating bugs. While they were setting up the camera and sound equipment I took a few moments to see what insects were visiting the bright yellow flowers on the bush I was standing next to. Among the usual honeybees, I saw a massive black fly. This fly was huge (3/4 of an inch in length) and really stood out against the yellow flowers.


It was a Mexican cactus fly, Copestylum mexicanum, feeding on nectar, and this was the first time I had seen them around the Museum!

Here's what Flower Flies of Los Angeles County book has to say about them:
"This is the largest flower fly in Southern California, with a body length of 18mm. It gets its name from the larvae that feed in wet decaying prickly pear...

The Hitchikers Guide to Los Angeles

Have you ever jumped in your car and realized there was a bug on your windshield? Not a gross squished one, I mean a living one, ready for a hitchiking adventure. When this happens, you might be like me, and decide to spark up the engine and see how long that sucker can stick around for (never speeding of course)! In my extensive experience, the bugs usually manage to "hang on" for much longer than one would expect. Case in point: This bright green katydida close relative to grasshopperstraveled with Nature Lab project manager, Jennifer Morgan, all the way from Palos Verdes to Pasadena, reaching speeds of up to 70 mph!   

Katy "done" did it right!

For a better idea of what a katydid looks like, here's an image courtesy of...

Psycho Spider Killer: What is It?

I've been waiting an entire month to write this post, and maybe my entire life to entomologically riff off a Talking Heads song title! On Monday, October 1, I found a large tarantula hawk wasp (a.k.a Pepsis wasp) on some flowering Baccharis in the North Campus. This blue wasp with orange wings was the first of its kind spotted in our new gardens, and is indeed a spider killer.

This is what Insects of the Los Angeles Basin has to say about tarantula hawks preying on spiders:
 
"When a female wasp finds a tarantula, she alights and engages it in battle. The wasp then stings the spider on the underside between the legs and usually succeeds in paralyzing but not killing it....

What's Up Goatsucker?

Yes, the first Goatsucker has been found in our new wildlife gardens! No, I'm not talking about a weird new species of goat parasite, I'm actually talking about a type of owl-like bird. Goatsuckers, a.k.a. nightjars, are members of the family Caprimulgidae, which comes from the Latin word Caprimulgus, literally meaning goatsucker. The Latin name came about because of the mistaken belief that these birds would swoop under milking goats to steal milk from the teat!

The L.A. River is Alive: From Mudbugs to Mallards

On Sunday, I joined two amazing people, Jenny Price and Lynn Garrett, on the Hidden L.A. River Tour. Yes people, L.A. does indeed have a river, one with real flowing water, real wildlife, and people like Jenny and Lynn, who are really passionate about it. It was an awesome adventure to explore our river with such knowledeable and enthusiastic people!

The morning started bright and early at 9 am at the L.A. River Center and Gardens, where many river-based non-profits have their offices. We quickly figured out the carpool situation, since it was a driving/walking tour of the river, and got a brief introduction that outlined the six rivery stops that were ahead of us. Without much further ado, we piled in our cars and headed to our first stop on the river.

We didn't have far to travel. The first stop was only five miles north of our starting point, and as we drove we followed the river's course (though we were travelling against...
