The Real L.A. Noir: The True-life Insect Cannibals and Murderers in our Midst

As you get into your car in the parking lot of the Trader Joe’s in Silver Lake in Los Angeles, you might just be within arm’s reach of cannibals. Not the human kind – but the insect variety.

Inside a wasp that is buzzing around a nearby bush dwells a bug known as the twisted wing parasite. These tiny insects are genetically close to flies and resemble nothing so much as a small black speck. But placing that speck under a microscope reveals huge, orb-like eyes that, as entomologist Emily Hartop puts it, look like sinister purple boysenberries.

Although the twisted wing parasite’s name comes from the seemingly malformed wings of the male of the species, the female has no wings. In fact, she has no legs, not even functional mouthparts – she is literally...

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...

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...
