Butterflies are self propelled flowers,
Verified Purchase(What's this?)
This review is from: Audubon Butterflies - A Field Guide to North American Butterflies (App)
After receiving Audubon Birds as the Free App of the Day, I was impressed enough by it to purchase several of the other Audubon Field Guide apps.
Like the Birds guide, there is so much information in the app it can be overwhelming if you try to browse through it like a printed guide book. And like the other Field Guide apps, this one has a search function to make it easier to identify a particular species, but in this app it is rather lacking. While the other Audubon apps have a dozen or more criteria you can search with, this app has only 5, shape, habitat, region, color and size. The shape criteria isn't much help if you're a novice, as there is no explanation as to the difference between, say, a Swallowtail and a Hairstreak. Searching by size is completely broken. I tried to search for a white and orange butterfly measuring 1-3 inches and it claimed there were no matches, but if I looked for one measuring 1.25-1.5 inches, it found over a dozen. Now, when I was in school, the range of 1 to 3 included 1.25 to 1.5.
The app lets you keep a life list, record sightings and take photos, and then upload them to AudubonGuides.com.
Because of the huge volume of data available, this app does require a data connection or a 250 MB optional download. If you choose not to download the data, it could chew up considerable bandwidth if you have a limited data plan.
Higher resolution images would be nice, since the difference between species is sometimes very subtle. More pictures of caterpillars and the ability to search based on caterpillar criteria would be nice.
While the app has a moth section, it appears to be mostly brightly colored moths such as the Luna Moth. I couldn't find any Pterophoridae (Plume Moths), for instance.
The app works well enough on my tablet, but it can't make up its mind whether it wants to run in landscape or portrait.
