Second Ant-decapitating Fly Found in Glendale

Our scientists found another species of ant-decapitating fly in Glendale, Pseudacteon amuletum!

Here's an account of this tiny, yet impressive fly, by Lisa Gonzalez, one of our BioSCAN entomologists:

"For those of you who missed Lila’s exciting account of the moment Dr. Brian Brown first spotted an ant-decapitating fly in one of our BioSCAN samples as it was being sorted in front of our visitors in the Nature Lab, please enjoy this post. As Lila so eloquently described, ant decapitating flies are tiny but mighty little phorid flies that lay their eggs inside of the bodies of, you guessed it, ants. Many of these specialized...

Ant-decapitating Fly Found in Glendale!

I just found out we have ant-decapitating flies here in Los Angeles! Dr. Brian Brown, the Museum's Curator of Entomology and one of the world's foremost experts on flies, made a chance discovery by looking right under the nose of an unsuspecting USC student.

It all started last Friday, while we were enjoying a nice stroll through the Nature Gardens. First, we checked out the Malaise trap that Brian and his staff set up as part of the BioSCAN project, which aims to survey the insect biodiversity here in Los Angeles. Then, we headed into the Nature Lab to see insects from this trap, and the 25 others that have been placed all over Los Angeles, being sorted.

As we got close to the demo table, Brian was suddenly transfixed. He'd seen...

Bee Sex in the Nature Gardens

In July 2011, our Curator of Entomology, Dr. Brian Brown, brought in some old redwood he had lying around his yard. He wasn't just trying to pawn off some lumber he didn't need anymore, we wanted it to make some bee hotels.  Jerome Brown, one of our amazing exhibit technicians, fabricated two hotels and Phil Bouchard personally drilled the over 200 quarter inch holes (about an inch deep). Thanks guys!

This spring we finally saw the first bees using the hotels! I was so excited, I jumped up and down, Brian did not, he just smiled. We watched as bees checked out the little holes and then I saw two fall to the ground. "Oh look they're fighting," I exclaimed. "No," Brian responded, "they're using the hotel like they...

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...

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...

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...

Kinky Bug Found in Museum's Gardens

 

I just got this e-mail from our Curator of Entomology, Brian Brown.
 
"I asked Entomology Volunteer Franesca Zern to concentrate on identifying true bugs from the North Campus Malaise trap. She just identified (through her own research) a new record for Los Angeles County, a mirid plant bug called Coridromius chenopoderis. This tiny, 2 mm long Australian bug feeds on plants, including beets and spinach, but is considered unlikely to be a pest. According to our colleagues at L.A. County Agriculture, this is the first report from here, although it is also known from farther south in California."

Are you Ready for the ZomBee Apocalypse?

Today, we launched our latest Citizen Science project, ZomBee Watch, in partnership with San Francisco State University. Yes, that's right folks, we want you to become a real life ZomBee Hunter! To inspire you to do so, sit back and relax while I tell you this epic story of zombification!

Dead honey bee parasitized by the Zombie Fly.
Can you see the white maggot emerging from the neck region?

In the darkness of night zombified honey bees (ZomBees) abandon their hives and embark upon a flight of the living dead! These honey bees, Apis mellifera, have been infected by the Zombie Fly, Apocephalus borealis, brethren of the nefarious ant-decapitating flies.

Kindergartner Finds Greater Yellow Underwing Moth on North Campus

This past weekend the Museum hosted the 26th annual Bug Fair. Over the course of 72 hours, more than 10,000 people visited us. These lucky visitors got to see, do, and taste many things. At Curator of Entomology Brian Brown's table, visitors were able to see the world's smallest fly from Thailand (oh and it just happens to be a brand new species in the genus Euryplatea). On our insect stage, they could meet Western Exterminator's bed bug sniffing dogs. If people were hungry, they could head outside and taste some insectuous delights including Orthopteran Orzo, a la Bug Chef David George Gordon, or wax worm salad prepared by entomophagy expert Dave Gracer. If they were interested in hunting bugs rather than eating them, we also held bug hunts out in the Erica J. Glazer Family Home Garden.

First Baby Oaks Sprout Up in the North Campus

The North Campus is the proud parent of some baby oak trees!

Baby coast live oak sheltered by wall

Carol Bornstein, our new Director of the North Campus Gardens, discovered a couple of oak saplings on one of her recent outdoor forays. The babies are coast live oaks, Quercus agrifolia, of which we recently planted several trees. We've also planted another species of oak, the Engelmann oak, Quercus engelmanni (we planted only three of this species). Both species reside in the section of the garden called the urban wilderness which is composed of several kinds of California native trees and shrubs.

This might be the mother oak!

Oak trees provide amazing habitat value,...
