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...

June Beetles and Night Lights

This last weekend I stayed at Table Mountain campground in the Los Angeles National Forest and was visited by a group of beetles. No, not the British pop group out on a time-travelling-night-time-forest jaunt – though that would be blog worthy indeed. My camp buddies and I were visited by a gang of 40 adult male scarab beetles!

Three of the gang, hanging out on our picnic table. No they're not eating our hot dogs, they prefer pine needles

But what are they, you may ask? They are Ten-lined June Beetles, Polyphylla decemlineata, one of California's largest and most conspicuous scarab beetle species. And how did I know they were all males? This species exhibits sexual dimorphism (a fancy way for saying males and females look differently), which is most noticeable in the antennae (sure you could look at...

Do you have Museum Malaise?

You better not! However, just in case you do I have a line of curative agents perfect for any and all afflicted with such exhibit ennui. The elixirs I speak of are our new L.A. nature exhibits, Nature Lab and Nature Gardens, and they're about to open on June 9!

I've written loads of posts about both exhibits, so I thought it might be interesting to have a guest writer this week (I swear it's not because I'm too busy)! Dean Pentcheff from our Research and Collections staff is going to answer the question that everyone will be asking when the Nature Gardens open, who's camping in that tent out there?

"Peek between the bushes in the Nature Garden and you’ll see what looks like someone’s overnight camping spot. We do host overnight sleepovers at NHM but we don’t do it in the garden (at least not yet). What’s going on here?

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...

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."
