Posted by Kirsten Pisto, Communications Spiders are sort of the worst best. Homes and backyards in the Pacific Northwest seem to be teeming with spiders during the fall season and dewy-dropped webs float oh so delicately between the sidewalk and your face. But don’t get all antsy (ahem… spidery), we spoke with Sue Andersen, zookeeper at the Bug World exhibit, to learn more about these incredible eight-legged beauties. Video: A colorful look at spiders. Produced by Kirsten Pisto/WPZ. Volunteer Jordan asks zookeeper Sue Andersen about her love of spiders and why everybody should appreciate them! Sue, you have to work with spiders every day at Bug World. Were you always at ease around arachnids? To tell you the truth, no. When I first started volunteering at Woodland Park Zoo, all I knew was that I wanted to become a keeper. My very first assignment was to help feed the golden orb weaver. They are long legged and they are web-builders, meaning they like to hang o...

Posted by: Rebecca Whitham, Communications, with Sue Andersen, Zookeeper It seems like every time we do a spider story, someone gets mad at us for having to see these creatures on their screen. But we’re going to help you learn to love spiders, starting with these baby golden orb weavers seen here at just one hour old! Photo by Ryan Hawk/Woodland Park Zoo. Spiders are good people. We talked with zookeeper, Sue Andersen, to get the scoop on these amazing critters on the occasion of the third egg case hatching in Bug World in the past two weeks. Photo by Ryan Hawk/Woodland Park Zoo. Seen here are golden orb weaver spiderlings, fresh out of their egg case. According to Sue, “spiders actually develop from eggs into what is termed post-embryos (affectionately called ‘eggs with legs’ by arachnologists!) within the safety of their egg case. By the time they emerge from their egg case, they are first instar (or stage) as these guys and gals are. At this stage they are looking ...

Posted by: Fred Koontz, Field Conservation; Sue Andersen, Zookeeper Since their arrival last April, Woodland Park Zoo's new gray wolves have been delighting visitors with their majestic appearance and playful behavior. The four canids , all female, are an important way for the zoo to help tell the story about this important and endangered species from the Northwest. It also very timely, as the state Fish and Wildlife Commission is considering a state-wide wolf conservation and management plan—a proposal that Woodland Park Zoo supports. Why Conserve Wolves? Gray wolves, also called timber wolves, historically were found throughout North America, but they were relentlessly pursued and killed so that by the mid-1930s wolves were on the verge of extinction in the lower 48 states. Following their 1973 listing as endangered under the federal Endangered Species Act, wildlife management efforts have enabled wolves to make a comeback in the Great Lakes and northern Rockies. Bio...

Posted by: Fred Koontz, Field Conservation; Sue Andersen and Amy Brandt, Zookeepers For Wolf Awareness Week, we’re giving you a glimpse into the fascinating dynamics within the zoo’s pack of wolves living in our award-winning Northern Trail exhibit. Did you know Woodland Park Zoo has had wolves in its collection for more than 60 years? The zoo’s wolves serve a critical role as ambassadors for their wild counterparts. The current pack consists of four female litter mates born at New York State Zoo in April 2010. They have four distinct personalities. When you next visit the zoo, see if you can identify them from their pack behavior: Doba is the pack's "alpha" or most dominant wolf. She is often visible in the front and center of the exhibit, where she can keep track of the other wolves. If you see a wolf gathering bones or toys that is likely to be Doba! Shila is the pack's most submissive member. She spends most of her time lying a bit distant from t...

Posted by: Sue Andersen, Zookeeper Early last month, Woodland Park Zoo Collection Manager Erin Sullivan and I took a road trip for conservation to release captive-reared caterpillars as part of a new zoo program to recover the wild populations of the state endangered Taylor’s checkerspot butterfly. The release into the wild may be the exciting and deeply rewarding climax to this pilot program, but the story begins with the arrival to the zoo of 510 very sleepy, fuzzy black caterpillars that were just waking up from almost six months of diapause (winter resting). The caterpillars were hatched and reared at Oregon Zoo last summer before entering the natural resting period late last summer. At Woodland Park Zoo, the larvae were set up in plastic bins where they were fed, watered, and carefully monitored for about 10 days. During their stay, the caterpillars ate like, well, very hungry caterpillars! Along with my fellow keeper Diane Abbey, we harvested nearly 100 plantago leaves per...

Posted by: Sue Andersen, Bug World Keeper Jumping stick babies hatched last week, and right now keepers are tending to them behind the scenes while mom and dad are on display in the Bug World exhibit. Here’s a sneak peek of what they look like: (That's baby on the keeper's hand, mom in the middle, and dad on the right) This amazing "stick bug" is actually a grasshopper species. This insect, native to the upper Amazon Basin of Peru and Ecuador, is a great example of sexual dimorphism, which in this case means the female and male look like different animals. The male is smaller and green with white "face" marking, and the female is several times the male’s size, tan-dark brown, and looks exactly like a stick! She even has markings that look like bud scars. The eggs of this species take nine months to a year to hatch, and the female oviposits them in the soil, burrowing her abdomen in the substrate all the way to her rear legs! Woodland Park Zoo has kept these ...

By Bug World keeper, Sue Andersen Looking every bit as fierce as their namesake, rhino beetles ( Dynastes granti - AKA the Grant's or Western Rhino beetle) are making their presence known in Bug World. These beautiful American beetles are found in the Southwest and are often found around mercury vapor lights near gas stations. After living as grubs for two-four years underground or in rotten logs, these beetles, olive green with numerous chocolate to brown spots on the wings, emerge to eat pollen, ripe fruit, and tree sap. The male beetle has impressive black horns with which he defends the hornless female against other potential suitors. These beetles are at increasing risk of over collection, habitat destruction, and eradication due to increased incidences of wildfires as a result of global warming. Our first two males recently eclosed, the third generation of zoo- bred beetles from ova laid in July 2007. A female pupa is being watched with eager anticipation!
