For a couple years now, I've been trying to learn all I can about butterflies. It all started in 2002 when I made it through a lazy, long summer day by playing hopskotch. While hopping around the cracked sidewalk, I saw a sadddle-back moth caterpillar! Then this year, I saw a Monarch butterfly breaking out of the sac its caterpillar had made on one of the arms of the front porch family glider. So I was really ready for CATERPILLARS IN THE FIELD AND GARDEN.
Authors Thomas J Allen, Jim P Brock and Jeffrey Glassberg know what they're talking about. They've studied, looked long and hard at, and lived with caterpillars and butterflies for years. They've also put all that book learning and field work into a clearly written, well organized guide with many helpful pictures.
Their book gives the English and scientific names, identification, host plant, habitat and garden tips for each of over 500 butterfly caterpillars. It also has good photos of each caterpillar and butterfly. But the authors warn that the pictures are of caterpillars when they're that close to making the sac from which butterflies break away. Based on the very few examples found so far, young caterpillars don't look that much like their older forms.
A female butterfly can lay as many as 100-300 eggs. But only about 1-2 will make it through life to become a butterfly. Too many will be killed by bacterial, fungal or viral diseases; or parasite flies and wasps; or people; or pesticides. Many of us now see the need to reduce pesticide and hazardous material use. With this book, we'll know butterfly caterpillars when we see them. So we'll know better than to spray and swat them.
What I take away from this beautiful work is how good butterfly caterpillars and butterflies are for us and our green spaces. Most caterpillars going after our salad or vegetable plants aren't going to grow up to be butterflies. Butterfly caterpillars and butterflies go for North America's native plants and trees. That's all they need, along with shelter from the wind, nectar, flat stones for sunning, and damp sand or gravel for salt. And their favorite pig-out food: fermenting fruits!
