house dust mite
- The subphylum Acarina
is among the most diverse and successful of all invertebrate
groups having exploited a vast range of life-modes and habitats.
- They reach sizes of
up to only 3mm, however, the largest trombiform mites can reach
up to 12mm in size.
- The earliest mites
have been found in the Devonian Rhynie
Chert of Scotland, however the best fossil mites are known
from Oligocene Baltic amber.
- Many species within
the Acarina are parasitic, some are aquatic inhabiting even marine,
as well as fresh-water habitats.
- Many Rhynie Chert
examples have been found preserved in empty plant sporangia suggesting
that some species had adopted a herbivorous feeding strategy
by the early Devonian.
