Orius

The genus Orius (commonly called minute pirate bug) consists of omnivorous bugs in the family Anthocoridae (pirate bugs). Adults are 2–5 mm long and feed mostly on smaller insects, larva and eggs, such as spider mites, thrips, jumping plant lice,[1] and white fly, but will also feed on pollen and vascular sap.[2]

Bites of Orius sp. after one day

These predators are common in gardens and landscapes. They have a fairly painful bite, but are not venomous.

Some species are raised commercially and sold to growers as a form of biological control.

In laboratory conditions, the larval development of Orius niger takes 14 days at a temperature of 25°; females have a longevity of 60 days and can lay up to 150 eggs.[3]

gollark: HELP ME I CANNOT DECIDE ON THINGS
gollark: <@332271551481118732> Your thoughts? The existing UI allows you to have multiple notes open, but it's quite buggy wrt. scrolling when you open new ones, is somewhat harder to implement than just having one page open at once, and arguably takes attention away from your notes' contents.
gollark: I still don't actually have login working properly, so if you're not logged in it'll just get stuck on "Loading..." and you have to manually send a POST request to the login API endpoint.
gollark: This is the minoteaur UI as of now.
gollark: I found a cool notes application called Standard Notes, and while I probably won't use it for unrelated reasons, it has a neat UI.
