Which butterfly field guides are best?
More than 700 of the world’s 20,000 butterfly species live in North America. We know that they are usually brightly colored and have striking patterns but rarely know more about them than that.
From a simple field guide for kids to a comprehensive resource on butterflies and caterpillars, field guides are a great way to learn more about how they behave throughout their life cycles. If you are looking for an in-depth and comprehensive guide, the National Audubon Society Field Guide to North American Butterflies is an excellent choice.
What to know before you buy a butterfly field guide
There are several ways to organize a butterfly field guide, so choose the approach you like best.
This is a popular way to match up the butterfly you see with the one in the book so you can learn more about it. Sections are devoted to reds, yellows, blues and so on. Starting with the section on blue butterflies, for example, you narrow down your identification by increasing levels of detail, such as light blue, dark blue and deep purple.
Butterflies have two pairs of wings: one set of upper wings and one set of lower wings. Their wings are one of five basic shapes. You select the wing shape that most closely resembles that of the butterfly you are watching and narrow your search from there.
- Milkweed butterflies have the well-known classic butterfly shape, where the upper wings are much larger than the lower wings. The most well-known butterfly, the Monarch, is a part of the milkweed butterfly family.
- Fritillaries have top wings that are only slightly larger on top than their bottom set of wings. Their name comes from a Latin word meaning checkerboard. Some resemble the Monarchs because they are also orange and black, but the patterns are quite apparent when you know what to look for.
- Longwings have long, slender top wings and short rounded bottom wings. They eat pollen in addition to nectar and sleep in groups at night, perched on twigs.
- Swallowtails have extended tail-like appendages and a very slender tip on their bottom wings. They are the largest type and there are about 600 species, with only about 30 of them living in North America.
- Whites and Sulfurs are small to medium-sized butterflies with rounded wings. They are mostly seen on sunny days flying close to the ground.
What to look for in a quality butterfly field guide
How big is the book?
Butterfly field guides may be small paperbacks with fewer than 100 pages that fit in a pocket or backpack so you can actually take them into the field with you. Because of their small size, these field guides will be streamlined, with only basic information on common species.
The biggest field guides have lots of information about life cycles, habitats, migratory patterns, foods and behaviors. This kind of comprehensive detail takes up hundreds of pages, usually making the guides too big to take into the field and more useful as detailed reference material back home.
What is the book made of?
To be truly useful as a take-along guide, your field manual needs to be small, lightweight and able to stand up to the elements. Paperbacks are small and light but are delicate. Hardbacks are sturdy but are usually used on larger books. Guides covered in vinyl are best for using outdoors.
How much you can expect to spend on a butterfly field guide
The least expensive butterfly field guides cost less than $10 and provide only a few basic facts about a limited number of common species. Midrange guides cost $10-$20 and the best cost as much as $40-$50. After that, the cost increases in relation to the collectible nature of the guide.
