You probably have seen the Banner ad and the Announcement in the Forum for the Los Angeles County Natural History Museum Bug Fair being held this coming weekend May 21 and 22. A click on these will take you to the Museum's website where many kid friendly activities such as bug hunts, bug cooking, performances, crawly creatures, bug inspired artwork, exotic insect collections etc. are featured.
There is no mention that many insect specimens will be for sale. Yes, there will be INSECTS FOR SALE by vendors so bring yourself, your family, some $, and take advantage of the opportunity to buy real insects from around the world for you and your children.
With A.Bic out of business and Derosa also out of business I very much doubt there are any large dealers left. Perhaps some small scale dealers and or collectors selling their sorted extra's, wholesale material, bred material, or personal captures. Bioquip bugs would probably be the only one there of any size --- if they were there. Most everything else about the show was probably the creepy crawly (oh' my) stuff which appeals to kids. I'm sure with the severe decline in true "collecting" interest along with little interest in books and the disappearance of large dealers; the show is probably a mere shadow of it's old self. And even the shows of the past were nothing like the grand affairs the Europeans have every year !
