To help aid in your collection expedition, we have provided an interactive map (below) where you can drag a marker around to find potential collection locations for your next expedition. Please read the information below to make sure you are collecting in legal areas!
Green areas on the map are locations you CAN collect from without a permit.
Red areas on the map are locations you can NOT collect from without a permit.
Gray areas on the map are locations owned by local government and so you will need to CHECK with your city or the county first. Let them know that Tetragnatha spiders are exempt of collecting permits from CA Fish and Wildlife.
Drag the marker around to see the GPS coordinate for that location and see if it’s an area that is okay to collect from.
The GPS coordinates will show on the bottom left hand corner of the map.
Locations that have already been sampled are indicated with a yellow dot.
