Citizen Science

Join us at Notes from Nature to capture data from the Essig Museum collection.

North American Butterflies

We are currently capturing North American butterfly data live at Notes from Nature. Many butterfly species are threatened in California (and globally) due to habitat loss, invasive species, climate change, pesticides, and other environmental assaults. To better understand these issues and how to reverse their effects we need to know when and where these species fly. Butterflies are not the only species threatened by environmental disturbance, but they are the ones we know most about. This is largely because they are often colorful and fly during the day – so they are easily spotted, and we notice when they disappear. With your help we can capture the 100+ years worth of data on butterfly distributions residing on the shelves of the Essig Museum. Sign in (or sign up) at today to help us capture these data.


Harnessing the Power of Crowdsourcing to Unlock the Data in Natural History Museums

Calling all citizen scientists – we need your help! Natural history museums around the world contain billions of insects that were collected over centuries. Each insect is tagged with a label that contains important information about when and where the insect was collected, species and collector names, and other useful data.

These data can be used to study insect population ranges, the spread of invasive species, and the response of insects to drought, fire, land use change, climate change, and other environmental disruptions.

The goal of the CalBug project is to digitize these data and make the information available to everyone. The first step in mapping out the distribution of California’s insects and spiders for the past 100 years is to take a picture of each specimen with its labels. If you live near UC Berkeley and want to help with this step, get in touch with us. The next step is to capture the information from these labels in our database. This is where we really need your help! It’s simple. Go to our Citizen Science web portal, Notes From Nature, and sign in (or sign up). Once you are signed in, look for the CalBug (California Terrestrial Arthropod Database) project, and read the instructions. You will be asked to fill in the country, state, county, locality, date, collector, and a few other items in an easy to fill out form, while looking at a picture of the specimen and its labels.
