9. Collection Reminder Today is April 6th. Your collections are due May 6th. In two weeks (April 20th), you will turn into me 10 orders and 18 families, properly curated and labeled, for a quiz grade. This is for your own good! I will correct any errors you are making. Next week we will go to Hornsby during lab time, and Stengl Lost Pines on the weekend. If you aren�t in collection mode, get that way.

10. O: Coleoptera Two Suborders: Adephaga (3 families) Carabidae Dytiscidae Gyrinidae

11. Adephaga First abdominal sternite divided by hind coxae Presence of distinct notopleural suture (junction between the notum and the pleuron)

12. F: Carabidae Ground Beetles Head at eyes nearly always narrower than pronotum. Antennae threadlike, inserted between mandibles and eyes. Generally black and shiny with striate elytra, but sometimes metallic or colorful 5-5-5 tarsal formula Often noctural, don�t confuse with Tenebrionidae

13. F: Dytiscidae Predaceous Diving Beetles (aquatic) Distinctive shape, elongate-oval; range from 1.2 to 40 mm in length. Hind legs flattened and fringed for swimming. Antennae threadlike, longer than maxillary palps Tarsi mostly 5-5-5. Trap air under the elytra to breathe underwater Don�t confuse with Hydrophilidae

14. F: Gyrinidae Whirligig Beetles (aquatic) Short, clubbed antennae. Looks like 2 pairs of eyes, 1 above and 1 below the water level. Forelegs long and thin; middle and hind legs short and paddlelike, not extending beyond margin of abdomen (only front legs visible in dorsal view). body elongate-oval and flattened, 3 to 15 mm in length. Tarsi 5-5-5. Common name comes from behavior of �whirling� like way of swimming Adults live near surface, larvae are aquatic predators.

15. Polyphaga Hind coxae do NOT divide 1st abdominal segment Notopleural suture generally absent

16. F: Buprestidae Metallic Wood-Boring beetles Hard bodied, elongate-slender to elongate-robust beetles, ranging from 2 to 40 mm in length. Many species metallic or bronzed in appearance, especially on the ventral surface. Antennae usually short and sawtoothed. Tarsi 5-5-5. Body shape somewhat characteristic Don�t confuse with Elateridae

17. F: Cerambycidae Long-horned beetles Long filiform antennae, ranging from one-half to over two times the length of the body. Body usually elongate and cylindrical; 2- to 60-mm in length. Often brightly colored Eyes generally notched with antenna arising within the notch. Tarsi apparently 4-4-4, really 5-5-5 with the 4th segment small and inconspicuous. Don�t confuse with Chrysomelids (have similar tarsi, but shorter antennae, rounder, and no notch in the eye)

18. F: Chrysomelidae Leaf Beetles Hard to characterize family- very diverse Elongate-subcylindrical to oval shaped beetles, 1- to 16-mm in length. Antennae generally less than 1/2 the length of the body. Eyes generally not notched. Tarsi generally appear 4-4-4, actually 5-5-5.

19. F: Coccinellidae Lady bugs, Lady bird beetles Most species with distinctive shape, strongly convex dorsally and flat ventrally. Tarsi appearing 3-3-3, but actually 4-4-4. Head often concealed by pronotum. Antennae short with a 3- to 6-segmented club. Predators of aphids and scale

20. F: Curculionidae Weevils Head usually with snout ranging from broad and flat in a few species to elongate and narrow in most species. Antennae usually elbowed and with 3-segmented club. Length from 0.6 to 35 mm, mostly less than 10 mm; body often covered with scales. Tarsi apparently 4-4-4, actually 5-5-5. Can be serious pests or beneficial herbivores, depending on species

21. F: Dermestidae Dermestids Typically small, 1-12mm Body covered in small hairs that rub off easily, usually patterned with bands or spots Distinctly clubbed antennae Larvae Are major pests of stored food (and of your collections!), are also useful in skeleton cleaning and are used in forensic entomology

22. F: Elateridae Click beetles Elongate, parallel-sided beetles, generally rounded at each end. Pronotum pointed on the posterior corners. Prosternum with a spinelike process that fits into a groove in the mesosternum. Prothorax and mesothorax loosely joined, enabling adults to arch, "click," and flip over when they are upside down. Antennae generally serrate, sometimes filiform or pectinate. Tarsi 5-5-5. Many buprestid species look like elaterids, but have the pro- and mesothorax tightly fused rather than separated and flexible.

23. F: Hydrophilidae Water Scavenger Beetles (aquatic) Antennae with 4-segmented club, usually well concealed, shorter than maxillary palps Hind legs fringed with "hairs". Metasternal spine present Adults 1- to 40-mm long; body oval or elliptical, convex dorsally. Tarsi 5-5-5 or 5-4-4. Few are found in moist terrestrial habitats Larvae are predaceous, adults herbivorous

24. F: Lampyridae Fireflies- not flies! Elongate, softbodied beetles, 4.5 - 20 mm in length. Head concealed from above by flattened pronotum (cf Cantharidae). Last 2 or 3 abdominal sterna often luminous. Tarsi 5-5-5. Flashing is part of courtship and mating- light produced by an efficient biochemical reaction

25. F: Meloidae Blister Beetles Head broad, generally rectangular when viewed from above. Pronotum cylindrical and narrower than both the head and base of elytra. Body elongate, soft and somewhat leathery- Elytra are not as hard as other beetles Antennae filiform or moniliform. Tarsi 5-5-4; claw either toothed or lobed. Common name comes from the blisters that result from an irritating substance they secrete when disturbed

26. F: Scarabaeidae Scarab beetles, june beetles, dung beetles Robust beetles varying greatly in shape; size ranging from 2 to 62 mm. Distinctive lamellate antennae; club generally 3 to 4 segments (max. 7) and capable of being closed tightly. Tarsi 5-5-5. Front legs with scallop-shaped ridges Range in colors from brown to metallic colors

27. F: Scolytidae Bark-beetles Cylindrical body Elbowed clubbed antennae that are relatively small. The head is commonly concealed, or partially concealed by the pronotum from above. Similar to the Curculionidae but distinguished from that family by their short (as opposed to long) snout and their more elongate, cylindrical form. In some genera there may be backwardly directed spines on the ends of the elytra. Can be massive pests on trees

28. F: Staphylinidae Adults elongate-slender, 0.7-25 mm. Elytra short, leaving 3 to 6 abdominal segments exposed. Tarsi usually 5-5-5 Don�t confuse with earwigs- these are beetles!

29. F: Tenebrionidae Darkling Beetles Eyes notched by a frontal ridge. Antennae usually 11 segmented and filiform, moniliform, or weakly clubbed. Tarsi 5-5-4; claws simple. Body form variable, ranging from elongate to oval and smooth to very rough. Adults and larvae are scavengers. Mealworms, a major pest of stored grain, belong to this family.
