Activities for the Tarantula Scientist
Activities for The Tarantula Scientist These activities were created by Leigh Lewis, a grade school teacher in Wynne, Arkansas. “Picture a Tarantula” is an activity that builds 1 observation skills. Students will listen to a description of a goliath birdeater tarantula and draw a picture from that description. This activity points out the importance of detail. It links science, reading/literacy, and art in a way that students love! “Classify, Classify, Classify” is an activity that can 2 be utilized in a variety of ways. Students will hear how living organisms are classified, and then they will look at the animals pictured in the book and decide how they should be classified. This is truly an adventure! Once students collect the data, they will organize the information in tables and graphs. Students can do this individually, or in groups. This activity links math, science and technology. “Creature Search” is an activity that combines 3 science, writing and reading. Students will be given a topic from The Tarantula Scientist to research. They will then do a written and oral report. As an added bonus students will be learning about many fascinating plants and animals that live in the jungles and rainforests that are rapidly being destroyed. The “Spider Crossword Puzzle” is a fun conclusion 4 to a great book. Students will read The Tarantula Scientist, and then put all of their newly acquired knowledge to use by filling in the puzzle. THE TARANTULA SCIENTIST by Sy Montgomery is published by Houghton Mifflin Company ISBN 0-618-14799-3 www.houghtonmifflinbooks.com PROJECT 1 Picture a Tarantula GRADE LEVEL: 4th-8th OBJECTIVE: TSW listen to a description of a Goliath birdeater tarantula from The Tarantula Scientist and tsw create a picture from the description. -

Note on Suspected Brown Recluse Spiders (Araneae: Sicariidae) in South Carolina
Faculty Research Note Note on Suspected Brown Recluse Spiders (Araneae: Sicariidae) in South Carolina Robert J. Wolff* South University, 9 Science Court, Columbia, SC 29203 The general public believes that brown recluse spiders (Loxosceles Filistatidae (Kukulcania hibernalis) 22 specimens reclusa) are widespread where they live and that these spiders are Lycosidae 21 (3 in one package, 5 in another) frequent causes of bites resulting in dermonecrosis. Research over the Pholcidae 17 past twenty years shows these reports to be unfounded. Vetter (2005) Miturgidae 8 examined 1,773 specimens sent in from across the U.S. as brown recluse Theridiidae 8 spiders and no specimens were found from areas outside the species Agelenidae 7 range, with the exception of a specimen from California. Araneidae 6 Clubionidae 6 The reported range of the brown recluse spider includes all or major Thomisidae 6 portions of Arkansas, Oklahoma, Texas, Louisiana, Alabama, Tennessee, Gnaphosidae 4 Kentucky, Illinois, Missouri and Kansas. Minor portions of the brown Corinnidae 3 recluse range were previously reported in Iowa, Indiana, Ohio, New Philodromidae 3 Mexico, North Carolina, Georgia, and South Carolina. The most recent Amaurobiidae 1 map (Vetter, 2015) does not include South Carolina, and only the far Pisauridae 1 western tip of North Carolina and northwestern corner of Georgia. Scytodidae (Scytodes thoracica) 1 Unidentifiable 4 Schuman and Caldwell (1991) found that South Carolina physicians reported treating 478 cases of brown recluse spider envenomations in 1990 alone. This seems like a very high number, unfortunately all or No brown recluses were identified from the specimens obtained in this almost all of these are probably not brown recluse spider bites. -

EENY299 Brown Recluse Spider, Loxosceles reclusa Gertsch & Mulaik (Arachnida: Araneae: Sicariidae)1 G. B. Edwards2 Introduction Kansas, east through middle Missouri to western Tennessee and northern Alabama, and south to southern Mississippi. The brown recluse spider, Loxosceles reclusa Gertsch & Gorham (1968) added Illinois, Kentucky, and northern Mulaik, is frequently reported in Florida as a cause of Georgia. Later, he added Nebraska, Iowa, Indiana and necrotic lesions in humans. For example, in the year 2000 Ohio, with scattered introductions in other states, includ- alone, Loft (2001) reported that the Florida Poison Control ing Florida; his map indicated a record in the vicinity of Network had recorded nearly 300 alleged cases of brown Tallahassee (Gorham 1970). recluse bites in the state; a subset of 95 of these bites was reported in the 21 counties (essentially Central Florida) under the jurisdiction of the regional poison control center in Tampa. I called the Florida Poison Control Network to confirm these numbers, and was cited 182 total cases and 96 in the Tampa region. The actual numbers are less important than the fact that a significant number of unconfirmed brown recluse spider bites are reported in the state every year. Yet not one specimen of brown recluse spider has ever been collected in Tampa, and the only records of Loxosceles species in the entire region are from Orlando and vicinity. A general review of the brown recluse, along with a critical examination of the known distribution of brown recluse and related spiders in Florida, seems in order at this time. Figure 1.

TARANTULA Araneae Family: Theraphosidae Genus: 113 Genera
TARANTULA Araneae Family: Theraphosidae Genus: 113 genera Range: World wide Habitat tropical and desert regions; greatest concentration S America Niche: Terrestrial or arboreal, carnivorous, mainly nocturnal predators Wild diet: as grasshoppers, crickets and beetles but some of the larger species may also eat mice, lizards and frogs or even small birds Zoo diet: Life Span: (Wild) varies with species and sexes, females tend to live long lives (Captivity) Sexual dimorphism: Location in SF Zoo: Children’s Zoo - Insect Zoo APPEARANCE & PHYSICAL ADAPTATIONS: Tarantulas are large, long-legged, long-living spiders, whose entire body is covered with short hairs, which are sensitive to vibration. They have eight simple eyes arranged in two distinct rows but rely on their hairs to send messages of local movement. These spiders do not spin a web but catch their prey by pursuit, killing them by injecting venom through their fangs. The injected venom liquefies their prey, allowing them to suck out the innards and leave the empty exoskeleton. The chelicerae are vertical and point downward making it necessary to raise its front end to strike forward and down onto its prey. Tarantulas have two pair of book lungs, which are situated on the underside of the abdomen. (Most spiders have only one pair). All tarantulas produce silk through the two or four spinnerets at the end of their abdomen (A typical spiders averages six). New World Tarantulas vs. Old World Tarantulas: New World species have urticating hairs that causes the potential predator to itch and be distracted so the tarantula can get away. They are less aggressive than Old World Tarantulas who lack urticating hairs and their venom is less potent. -

2010 Rust and Vetter. Influence of Spider Silk on Refugia Preferences of the Recluse Spiders Loxosceles
HOUSEHOLD AND STRUCTURAL INSECTS Influence of Spider Silk on Refugia Preferences of the Recluse Spiders Loxosceles reclusa and Loxosceles laeta (Araneae: Sicariidae) 1 RICHARD S. VETTER AND MICHAEL K. RUST Department of Entomology, University of California, Riverside, CA 92521 J. Econ. Entomol. 103(3): 808Ð815 (2010); DOI: 10.1603/EC09419 ABSTRACT In a previous experimental study, recluse spiders Loxosceles reclusa Gertsch and Mulaik and Loxosceles laeta (Nicolet) (Araneae: Sicariidae) preferred small cardboard refugia covered with conspeciÞc silk compared with never-occupied refugia. Herein, we investigated some factors that might be responsible for this preference using similar cardboard refugia. When the two Loxosceles species were given choices between refugia previously occupied by their own and by the congeneric species, neither showed a species-speciÞc preference; however, each chose refugia coated with conspeciÞc silk rather than those previously inhabited by a distantly related cribellate spider, Met- altella simoni (Keyserling). When L. laeta spiders were offered refugia that were freshly removed from silk donors compared with heated, aged refugia from the same silk donor, older refugia were preferred. Solvent extracts of L. laeta silk were chosen approximately as often as control refugia when a range of solvents (methylene chloride:methanol, water, and hexane) were used. However, when acetone was used on similar silk, there was a statistical preference for the control, indicating that there might be a mildly repellent aspect to acetone-washed silk. Considering the inability to show attraction to chemical aspects of fresh silk, it seems that physical attributes may be more important for selection and that there might be repellency to silk of a recently vacated spider. -
