4. The Milkweed Plant is the host for the larva of the monarch butterfly. The plant produces a poison to keep animals from feeding on its leaves. But the monarch caterpillar can feed on this plant, and it uses the poison from the plant to protect itself from birds who like to eat caterpillars. Asclepias - milkweed

12. Drosera filiformis is a species of sundew found in acid bogs along the southeastern costal areas. This one lives in NJ. The acid water does not allow this plant to remove minerals from the boggy soil, so this and many similar plants have evolved a carnivorous lifestyle. The leaves attract, attach, and digest animals alive to mine their bodies of minerals. The leaves do not retrieve carbon or energy from the animal, just mineral elements normally obtained by plants from soil.`

13. Drosera rotundifolia is the more-common sundew in CT

14. ©1996 Norton Presentation Maker, W. W. Norton & Company Drosera (sundew) uses sticky pads that look like nectaries but are actually glandular hairs secreting botanical super glue with digestive enzymes: Remember that carnivorous plants are not eating insects for energy or carbon… they are mining the insect bodies for minerals unavailable from the acidic bog soil.

15. Sarracennia purpurea digests animals in rainwater held in pitcher-like leaves

16. ©1996 Norton Presentation Maker, W. W. Norton & Company Saracennia (pitcher plant) leaves hold water to drown insects and mine their bodies for minerals Soil pH is less than 4

17. Dionaea muscipula is a Carolina species It is rare and endangered today!

18. ©1996 Norton Presentation Maker, W. W. Norton & Company Dionaea (Venus fly trap) leaves have evolved three trip hairs on each half-blade, an electrical potential is produced, osmosis causes the trap to snap shut, This fly is about to touch the second trip hair… Soil pH is less than 4

19. ©1996 Norton Presentation Maker, W. W. Norton & Company The trap halves have folded together, and the marginal spines have turned inward…the compound action makes an effective trap…have you ever tried to catch a fly?

20. Utricularia is an aquatic carnivorous plant, each bladder having a trap door to suck in swimming animals Bladderwort is very common in CT lakes! http://www.fs.fed.us/wildflowers/plant-of-the-week/images/commonbladderwort/utricularia_macrorhiza_bladders_lg.jpg http://www.paflora.org/Utricularia%20inflata2.jpg http://tncweeds.ucdavis.edu/photos/utricinfla06.jpg
