Numbers

Larvae parasitize insects and arachnids of all major orders. Adults eat insect eggs. Host associations summarized in(3)
Remarks
From Zhang(3)(1998):
"The Trombidiidae and allied groups are poorly known taxonomically and their classifications are among the most difficult in the Prostigmata. Many species are known only from adults or deutonymphs, some species are known only from larvae and only a few species are known from both the larval and post-larval stages."
