Jeff's Cooties

Last Wednesday our Horticulturist, Jeff Leonard, received a walkie-talkie call from the reception desk. "Jeff, your cooties are here." For anyone overhearing this conversation and wondering - Jeff's "cooties" are, in fact, "beneficial insects." About once or twice a year Jeff orders "bennies" as he calls them, to keep control of aphid, scale, mealybugs and other harmful pests on the plants in the Tropical Butterfly House. This spring's shipment contained four different species. Encarsia formosa is a parasatoidal wasp that attacks aphids, white flies, and other small pests. The eggs arrive on small tags that are hung around the limbs of the infected plant. When the eggs hatch, there is a banquet waiting for them.

Lindorus lopanthae, black lady beetles are scale slayers. These bennies arrive in small vials and are carefully placed on the plants near contaminated sites. The bugs get to work immediately upon release!Cryptolaemus montrouzieri are better known as mealybug destroyers. They are similar to ladybugs but smaller - less likely to leave with visitors.

Chrysoperla rufilabris, green lacewings are probably most recognizable as adults. These beneficial insects arrive as ravenous larvae in cardboard combs which are tapped onto aphid infested plants. If you could see them close-up (which is hard to do because when they arrive they’re less than 1mm and grow to 6-8mm), you'd see the pinchers they use to suck the body fluids from their prey.

******

Controlling plant pests with beneficial insects means that our horticulture staff doesn’t have to use chemical pesticides or invasive processes in our Tropical Butterfly House. The butterflies are happy, the plants are happy and the “cooties” are happy!

Naked Mole Rats' Bedding

Observant staff and visitors have noticed that the bedding for the Naked Mole Rats has changed. The former medium, Aspen shavings, has been replaced with bedding made from the recycled cellulose pulp fiber CareFRESH®. Why? Well, like all scientists, we’re experimenting in search for the best setup for our colony. Our new bedding is produced in a cleaner, more controlled environment and is purpose-made as rodent bedding. What we did not know is whether it would work for our unique situation.

According to Life Science Department manager, Sarah Moore, “CareFRESH® bedding is working OK except that it is drier than the wood shavings. When we first introduced it to our Naked Mole Rats, their skin became flaky and dry. Now we’re tossing a small amount of filtered water in with the bedding to cut its moisture-wicking properties. Doing this has helped with the skin problems and it keeps their food from drying out too fast. Also, this new bedding does not absorb odor as much as the wood chips. But that is probably desirable in the case of mole rats, because they use odor as a marker.”

As caretakers of an animal with a complex social behavior, we’re trying to balance the mole rat’s physical husbandry needs (for a clean habitat with a stable temperature and humidity) with their social needs to be together and have minimum handling in an environment that smells like home.

The Bees are Back

Pacific Science Center has been maintaining an observation beehive for many years to increase the public’s awareness and understanding of honey bees. Every winter our observation beehive is vacated because of the challenges of maintaining an exhibition colony year round. Last week, Life Sciences staff dismantled and cleaned the display case in preparation of the arrival of our new residents.

Then early Saturday morning May 9th, beginning at 7am our apiarist John DeGroot and his assistant, Scott Enright arrived with our new colony. The installation must be done before Pacific Science Center visitors arrive. The cool, early morning temperature kept the bees calm.

Under the direction of Life Sciences manager Sarah Moore, the apiarists first open the beehive that John has brought. Next the men carefully lift out each frame from the hive box while searching for the queen. The queen is then carefully placed into a container for John to mark her thorax with a yellow pen. This doesn’t hurt her and helps our visitors find the queen among the thousands of other bees.

Once the queen has been marked, the enclosure is slowly and carefully reassembled. The eight frames of comb are placed in our vertical hive that is covered in glass and viewable on both sides. Up until now, the entire operation has been performed outdoors. Any straggler bees will find their way back to queen once the hive is in place.

When everything checks out, the frame is lifted up on a cart and wheeled back through the Insect Village to the awaiting exhibit structure. When the entire hive is set into the structure, slides that cover flight holes are removed so that the bees can freely come and go through a Plexiglas tube to the outside world.

A final check must be made of every potential leak to the system. Bees are capable of finding very small cracks in our exhibit which could upset them and our visitors. These potential escape routes have to be sealed with the best means possible: duct tape.

With the entire system in place, our new bees are free to fly around the Seattle Center neighborhood gathering pollen from the many flowers that bloom all summer long.

Visit our observation beehive and watch as the queen and her workers fill the frames with larvae and honey.

May Butterfly of the Month

Dryas iulia

Julia longwing or Passion vine butterfly

Range: Southern United States to tropical south America

• These butterflies are known for their erratic flight patterns. In the wild they are often found in the open clearings of forests.


• Julias are in the family Heliconiidae, along with all other species of longwing butterflies. Although they resemble other heliconius species, they have a distinct wing shape and solid orange color that makes them quite easy to identify.


• D. iulia eggs are laid on passion vines. Eating this hostplant during the larval stage will give the butterfly a flavor that is noxious to its predators. Can you think of other butterflies that use this method of defense?


• The Tropical Butterfly House gets Julia butterflies from both central and south America with colors that are very different. Though both are orange, the butterflies from Suriname have a pinkish cast that is almost neon bright!

Check out the Newest Members of our Tidepool

On Monday April 27, an intrepid group of naturalists from Pacific Science Center headed to Indianola beach to replenish our tidepool population. Taking advantage of exceptionally low tides, the team returned with an amazing assortment of anemones, arthropods, echinoderms and mollusks.

Come visit the newest residents of our Puget Sound Salt Water Tidepool. Friendly PSC Science Interpreters are happy to share their knowledge of these wonderful intertidal organisms.

We have lots of Hermit Crabs

Mossy Chiton visiting Christmas Anemones

A tiny Ochre star

This year’s collectors from the Life Sciences department included Brianna Todd, Adrian Eng and Maida Ingalls. Pacific Science Center staff Portia Lingwood and Sarah Bradshaw helped collect as well.

As in the past, we are grateful to PSC volunteer John Aurelius and the Indianola Beach community for allowing us to collect permitted animals from their shores.
