One of our campers took this shot of a butterfly in our meditation garden, and he’s only 8! My guess is that this is a Painted Lady Butterfly.
There are over 250 species of butterflies in the Sonoran Desert. This is partially due to the presence of indigenous (live here year around) and influx (travel here) species. Butterflies, along with other insects, like bees, and mammals, like bats, are important pollinators.
According to the Desert Museum:
They are also good indicators of the ecological quality of a habitat, as they are important components of the food chain, particularly as larvae. Few butterflies are a serious threat to economically important plants. In short, butterflies are benign, aesthetically pleasing, faunal members. In turn, the main threat to butterflies is the destruction and loss of their habitats. The channelization of riparian areas, draining of wetlands, lowering of water tables, growth of cities, and expansion of agriculture all contribute to this habitat loss. Widespread use of pesticides may also threaten healthy butterfly populations.
