Frass and Frass Gas (169 words) |
 | The Frozen Frass Force cocoons can be placed in your cooler, tackle-box or the bottom of the boat. |
| And, they help keep the Frass off of your hands while you bait the hook. |
| Large capsules containing between 6-8 catalpa worms are also available, great for baiting trot lines and cat-fishing on the banks of the river. |

| To analyze the frass, Morton used a mass spectrometer, which breaks down compounds into a chemical component "fingerprint." He discovered the beetles feed on, or more accurately, metabolize the sugars that plants often attach to alkaloids when they store them. |
| Chemical analysis of this larva's frass showed high levels of a substance that very closely resembles a compound called phytol, which is found in all plants. |
| Because phytol is found in more species of plants than are alkaloids and because the alkaloid-containing plants are a relatively recent addition to the flora, Morton believes that the beetles using phytol in their fecal shields might represent an earlier stage in the evolution of insect chemical defenses. |
