Do not eat your pet puffer. In consequence of their peculiar body plan, puffers do not swim as do most fish by curving and flexing the body. Most slow swimming is performed by the pectoral fins, with steering and stability provided by the dorsal, anal, and caudal fins.
Aphids in home gardens. Aphids are one of the most common insects found on plants. There are over 300 species of aphids found in Minnesota; they can be common in home gardens on vegetables, annuals and perennials.
The flowers, especially the yellow blooming varieties, act as a trap for aphids. Petunias repel asparagus beetles, leafhoppers, a range of aphids, tomato worms, and a good many other pests. Use sunflowers as a way to draw aphids away from other plants. Ants move their colonies on to sunflowers.
