We have developed a free PNW Moths Android app has no in-app ads. To use the PNW Moths Android app, first download it from the and install it on your Android device.(PNW Moths) to use to identify the >1,200 moth species found on this website. Unlike many free apps, the
The PNW Moths Android app allows one to make identifications based on a variety of features relating to location, date, size, shape, and the colors and patterns on the wings and body. To make it as user-friendly as possible the PNW Moths Android app has examples to illustrate each feature, but if you come across terms with which you are unfamiliar, you may also find the Glossary on this website helpful. Also, unlike with a traditional dichotomous key, the order in which features are selected does not matter, meaning that you can choose from the features with which you are most certain.
Identifying a Moth Back to top
When you open the app, it will look like this:
From there, you have the ability to take a photo of a moth and then use the app to identify it or you can just use the app to identify a moth without having taken a photo of it.
To take a photo, touch the Camera icon on the bottom menu and then touch one of the four larger camera icons on the camera page. Doing so will open up your device's camera, allowing you to take a photo. If you are satisfied with the photo, select OK, and then the photo will be added, like this:
Next, touch the Identify icon (moth with question mark) on the bottom menu and then use the scrollable menu across the middle of the page to see the choices of features relating to Distribution, Seasonality, Overall Size, Wing Shape and Size, Forewing Color and Pattern, Hindwing Color and Pattern, Abdomen and Thorax, and Eye Hairiness. Touching any of these menu items will open up a submenu that may have one or more features nested in it. In the example below, Distribution has been selected, and within that, the option of In Which Ecoregion In Washington? has been selected. Under that submenu, there is a scrollable list of possible answers.
If you are unsure of how to answer a question, you can use a long touch of each answer to see an image illustrating what is meant by that answer, as shown here:
To select an answer, touch it briefly to highlight that answer. It is possible to highlight multiple answers to a given question. Doing so will retain more possible matches because the key interprets a selection of multiple answers as OR, not AND.
In most cases, there will still be many possible species after your initial selection. In this case, selecting Columbia Plateau narrowed the list to 650 matches. To narrow the list further, you will need to select from more features. The app will show you the matching species only after the list has been narrowed down to 20 or fewer possible matches. You can scroll through this list of images to find one that matches your moth or you can reduce the list further by choosing from more features.
If you are uncertain how to distinguish among similar species or if you want to read more about the species you have identified, this website has detailed descriptions of each species. The fastest way to find a particular species on this website is to use your browser's search function on.
If you are identifying a moth that you have not taken a photograph of using the app, touch the Identify icon on the bottom of the blank opening page, and the feature menu will appear (allowing you to follow the same steps for identification as described above) but you won't see a photo in the upper left portion of the page. At this point, the Identify page will look like this:
Once you have identified a moth, you can record the information on your observation and identification for future reference. To record this information on your device, touch the image of the matching species, after which you will be asked if you want to add your observation. Approving this addition will record your observation, allowing you to add it to a searchable list of prior observations. To see the locations of your prior observations of this species, select the Map icon on the bottom menu and enter the species name, as shown here:
You also have the option of uploading your observation to the PNW Moths Android app server. Doing so will record your photograph(s) of the moth and the date and location of your observation. No other information is recorded when you upload your observations. Observations recorded to the PNW Moths Android app server are not shown on this website. To record your observation to the PNW Moths Android app, select the Observations icon (third icon from left), and then select Upload.
