Zootermopsis angusticollis is a species of termite (Order: Blattodea (formerly 'Isoptera)[1]') in the family Archotermopsidae, a group known as the Pacific dampwood termites, or the rottenwood termites. As their name suggests, the dampwood termites can only survive by living off of wood that contains high amounts of moisture. They are found along the wet environments of the Pacific coast of North America. Most are found in the states of California, Oregon, Washington, Idaho, Western Nevada and in southern British Columbia. Termites are well known to be destroyers of wood, and although the dampwood termites can cause some damage, they are not as notoriously known to cause as much damage to buildings as the drywood termites. They occasionally have been carried to other parts of the country through wood shipments, but have not been able to become established in these areas due to undesirable environmental conditions.
Zootermopsis angusticollis is a hemimetabolous, diploid species. Upon hatching from their egg, they are quite similar to adults except for their lack of genitalia. Their series of morphological instars allows them to increase in size until they reach their... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pacific Dampwood Termite sighting in San Francisco on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 336th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pacific Dampwood Termite in San Francisco on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Pacific Dampwood Termite sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
4th of 4
Of the 4 cities where we can rate Pacific Dampwood Termite sightings, San Francisco ranks 4th at under 5%. The best odds are in Seattle (United States, about 10%), Portland (United States, about 10%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Pacific Dampwood Termite is recorded against all the insects logged in San Francisco (22 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
