When the University of California, Davis, celebrates its annual Picnic Day on Saturday, April 17, be sure to check out the bugs.

Entomologists will showcase insects at the Bohart Museum of Entomology at 1124 Academic Surge on California Drive, and at Briggs Hall, off Kleiber Drive, from 11 a.m. to 4 p.m.

Matan Shelomi, a first-year graduate student in entomology whose major professor is Bohart director Lynn Kimsey, is quite fond of the walking sticks at the insect museum. Just ask his colleagues.

This one below is a giant lime green walking stick (Diapherodes gigantea) from the Lesser Antilles, from Guadeloupe to Grenada. The females are a bright green and about 17 centimeters long, while the males are about 11 cm and a dull brown.

Their diet: eucalyptus.

They do not eat little children.

The Bohart, home to seven million insect specimens, also has other live insects, including Madagascar hissing cockroaches, Vietnamese walking sticks, spiders, tarantulas, scorpions, and newly emerged mantids.

At Briggs, you can participate in the cockroach races, "Maggot Art" (a trademarked educational activity coined by UC Davis forensic entomologist Rebecca O'Flaherty) and termite trails (watch termites follow the "pheromone"). You can also check out the kissing bugs, bed bugs, fleas, ticks and assorted other critters.

Here's more information on what the entomologists are planning on Picnic Day.
