These Walking Sticks Are Insects

May 7, 2009

Brian Turner, outreach coordinator at the Bohart Museum of Entomology, UC Davis campus, is used to walking around with a walking stick.

Not just any walking stick. The Giant New Guinea Walking Stick and the Vietnamese Walking Stick.

Although the Bohart Museum houses more than seven million insect specimens, some are quite alive, thank you. They include the walking sticks, Madagascar hissing cockroaches, giant cave cockroaches, black widow spiders, and the rose hair tarantulas.

All are taking a brief "vacation" from the Bohart and are now housed in the floriculture building at the 134th annual Dixon May Fair, being held May 7-10. 

When Turner delivered them to the fair Wednesday afternoon, the insects drew excitement from exhibitors setting up floral displays. They marveled at the size of the spiny Giant New Guinea Walking Stick (Eurycantha calcarate), which can reach 6 inches in length. 

The male has large spikes on its back femurs. The female has what looks like a large stinger, but it really is an ovipositer (egg-laying structure). 

These insects dine on bramble, rose and guava.

They do not dine on fairgoers.
