Mites, Ticks & Pseudoscorpions

Mites are a hugely successful group with a large number of species. Mites are among the most diverse and successful of all the invertebrate groups, but because of their small size (most are microscopic) go largely unnoticed. They have exploited many habitats. Many live freely in the soil or water, but there are also a large number of species that live as parasites on plants, animals, and some that feed on mould (fungi).
Ticks are blood-sucking ectoparasites, mostly of mammals and birds. They wait on grass or bushes, and jump onto passing animals. A number of birds specialise in picking them off larger animals: the Cattle Egret and the Oxpecker for example. They are quite serious pests, and can be hard to get rid of. They are vectors, carrying diseases such as Lyme disease.
Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are tiny, and are rarely noticed due to their small size, despite being common in many environments. When people do see pseudoscorpions, especially indoors, they are often mistaken for ticks or small spiders.

Eriophyes tiliae is a mite that forms the lime nail gall or bugle gall.[2] It develops in a chemically induced gall; an erect, oblique or curved distortion rising up from the upper surface of the leaves of the common lime (linden) tree Tilia × europaea.

During late spring and summer, tubular growths up to 5 millimetres (0.20 in) long develop on the upper surface of lime tree leaves. These galls are yellow-green or red in color, may be very numerous, and predominantly occur on the lower leaves in some sub-species.

The galls appear not to affect the health of the lime trees, and no way of controlling or preventing them exists
The mites move onto the foliage in the spring, having overwintered in the bark crevices or around buds. These gall inducers are less than 0.2 mm long, however the chemicals they release while sucking the sap from the lower leaf epidermis have a dramatic, consistent and colourful effect, causing upward growing, hollow, yellow, red or pink, finger-like extensions. Before the autumn, the mites, which up to now have been actively feeding and growing inside the galls, depart from these shelters and seek protected sites elsewhere on the lime tree. The mites will pass the winter in such locations and then the cycle will be repeated. This species is one amongst a number of gall-formers which can be superficially similar in appearance; however E. tilae tilae is restricted to lime trees
