Spider mites are a diverse group of arachnids that can also spin webs. They can be particularly troublesome in greenhouses & can adversely affect crops as diverse as strawberries, melons, beans, tomatoes, eggplant & ornamental flowers.
They are quite small, ranging from 0.5 to 1.5mm & their presence or feeding marks on the undersides of leaves can be mistaken for tiny dots. They can be readily distinguished from aphids & thrips with this simple 10X magnifier.
Good IPM practice requires accurate identification in order to monitor mite infestation levels before attempting control whether with miticides, soapy water or predatory mites

Just the best on the market! Great quality, durability. I use this for more than 10 years with my students for field work.
We use this model in two introductory courses (a general geology course for engineers where 4 exercises cover minerals and rocks, and a mineralogy courses taken by a wide range of students in arts and science programs). Some students prefer its wider field of view to that of the other model we order from Indigo Instruments (their 17-mm glass lens, screw-hinged metal loupe). This loupe is durable, and can stand years of sharing among students learning their minerals and rocks in the classroom. Not designed to be worn on a lanyard, though.
