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."

But that's not all! Brian left Museum staff with this interesting tidbit:
"One interesting thing about these bugs is that they have traumatic insemination, like bed bugs. I won't broadcast the details, but yes it is as kinky as it sounds!"
Although Brian won't broadcast the details, I will! Traumatic insemination, aka hypodermic insemination, is a mating practice employed by some kinky invertebrates, bed bugs being the most notable. The male insect pierces the female's abdomen with his sword-like penis and injects sperm into the abdominal cavity. The sperm diffuses through the hemolymph (insect blood) and eventually reaches the ovaries. Hey presto, we've got fertilization! As you can imagine this process is no cake walk for the female insect in question. It creates open wounds which often lead to infection, thus shortening life expectancy. There we have it folks, another post about kinky InSEX.

Piranhas are the stuff of B-movies, sensationalized nature television, and the tropical rainforest. Most would think they have little bearing on life here in L.A., however as I learned last week, this is not the case.
Taxidermied Red Piranha, Pygocentrus nattereri "lips" removed to accentuate teethPiranhas are here in L.A.! They are sometimes confiscated from pet stores and, on occasion, they are even found in our waterways. The Museum's Ichthyology collection houses over 30 confiscated piranha, and at least one that was caught in the "wild." According to the collections record, this Red Piranha (see below) was netted from "Simi Valley Public Golf Course, Lake B." It was collected on April 28, 1988 and measured 275mm (almost 10 1/2 inches)! Most interestingly the capture method box of the record states that that the "fish was in distress." I wonder if the piranha would ever have been discovered had it not been in distress? Before any of us decide to never go fishing for our wayward golf balls with our bare hands again, I have some happy news. Even in the Amazon basin, where Red Piranhas are native, humans are extremely unlikely to be injured by them, let alone die. The image of a school of piranha stripping all flesh from a whole cow or indeed a whole human, isn't much more than a sensationalized Hollywood gimmick (think James Bond's You Only Live Twice). This is because Red Piranha are actually scavengers preferring to eat dead, not living flesh. So next time you're fishing for your golf ball in the water trap, be safe in the knowledge that you're much more likely to get bitten by your neighbor's dog!
The Simi Valley Golf course piranhaOther piranha collected in L.A. come to the Museum directly from the California Department of Fish and Game (CDFG). CDFG staff often patrol pet stores and upon finding illegal creatures will confiscate them under California Law Title 14 Section 671. The fish are promptly brought to the Museum for identification and sometimes for permanent storage, though they may be taken briefly into a court of law as evidence! In May 2002, the Museum received 16 Red Piranha specimens confiscated from one pet store alone!

We're taking the Museum outside! A new outdoor nature area is sprouting up around the Natural History Museum, bringing a fun and interactive park and habitat area right into the heart of the city. Think of it as the city's new backyard, filled with a range of garden environments and interactive opportunities for visitors of all ages to watch birds and search for bugs, stroll along a creek, ramble through a grove of trees, and gaze at butterflies and bees in a new Pollinator Garden.
For more details about the Nature Gardens project check out our website.
