The small size (<1.5 mm),
thigmotactic behavior, and adaptability of this thrips to a wide range of climatic conditions help explain its high invasiveness and on exotic pest lists of many countries.
This hypothesis is consistent with Patten's (1973) observation that copper rockfish on a small low-relief rocky reef in Puget Sound were more
thigmotactic in the winter and spring.
This
thigmotactic, shelter-seeking behavior may have led to a broader preference range, obscuring the effects of the acclimation temperature.

thigmotactic walruses snuggle together on shingle beaches and diminutive purple saxifrage grow in ancient whale graves, to the brilliant 30m ice cliffs of Brasvellbreen, caving to form a sea of Slush Puppy.

Small-bodied taxa (e.g., Hydroptilidae, Chironomidae) and taxa that are strongly
thigmotactic (react negatively to light; e.g., Hirudinidae, Gammaridae) characterized the main channel where didymo was abundant.
To simulate natural habitat conditions and accommodate the amblypygids'
thigmotactic preferences, cork bark lined the walls of the aquaria.
There is a wonderful word for their desire to feel the walls of cracks and crevices tight against their backs and bellies:
thigmotactic.
