War of the Larvae: Ladybug Grub Eats Flower Fly Maggot!

Urban Nature Research Center (UNRC) co-director Dr. Brian Brown recently wandered out of his home into his Monrovia backyard and caught sight of something unexpected on the outside of his insect trap: an immature ladybug (also known as a larva or grub) consuming the larva of a flower fly (also known as a maggot).  The large, tent-like Malaise trap—used in the UNRC's BioSCAN project to collect and study flying insects from multiple sites across Los Angeles—has a sloped, white mesh cover that serves as a perfect backdrop to capture an image of a bristly black and orange ladybug larva mid-meal....

Ladybug Love Fest on Top of the World

Valentine’s Day came early this year for these amorous Convergent ladybugs. Photo credit: Lila Higgins.

Last weekend on a hike to Sandstone Peak, the highest point in the Santa Monica mountains, fellow bug enthusiast Lila Higgins came across a brazen beetle Bacchanalia in full midday swing. Hundreds of ladybugs had gathered on a rotting log where they had previously been “chilling out” for several months. Hippodamia convergens, known as the Convergent ladybug, exhibits this adaptive behavior; these ladybugs will migrate in the fall to higher elevations to overwinter in large aggregations consisting of thousands of individuals. Just as the unseasonably sunny weather inspired Lila to go for a hike, the ladybugs awoke from their rest feeling frisky and ready for...

Rare Nine-spotted Ladybug Found in L.A.!

During Bug Fair, I found a ladybug in the Museum’s Nature Gardens, that didn’t look familiar. It didn’t have any spots, but it somehow looked different than all the other no-spotted ladybugs I’d seen before. I took its photo, posted it to our Nature Gardens Survey on iNaturalist, and then totally forgot about it.

It wasn’t until a few weeks later, while I was preparing for a behind-the-scenes tour in entomology that something made me come back to that photograph. I was planning to talk about a big discovery made by a citizen scientist back in 2009—the time Harsi Parker discovered a rare nine-...

Dinosaurs Open Part of North Campus!

Unless you're living in a cave somewhere (no offense to the troglobites out there), you've heard that we're opening a new Dinosaur Hall next week. In anticipation of this meteoric occasion all Museum staff were invited to preview the hall, which began with a jaunt through the soon to be open sections of the North Campus (car park, transition garden, entrance plaza, and footbridge). Even though these areas of the North Campus were only recently planted, we're already noticing wildlife visiting, including a ladybug that landed on me during the preview and another cat caught on camera trap!

Lost Ladybugs?
The ladybug that landed on me during the staff preview was a Multicolored Asian Ladybug, Harmonia axyridis. It's an introduced species from Japan, which has...
