In the context of ecological literacy, arthropods and other small invertebrates are often referred to by informal names such as minibeasts, bugs, creepy crawlies (-ie and -y in the singular), or minifauna (contrasting with megafauna). [1] The term is used for spiders, insects, woodlice, centipedes, slugs, snails, worms and many other animals.
Tardigrades lack several of the Hox genes found in arthropods, and a large intermediate region of the body axis. In insects, this corresponds to the entire thorax and abdomen. Practically the whole body, except for the last pair of legs, is made up of just the segments that are homologous to the head region in arthropods. This implies that ...
The young can frequently be found on herbaceous shrubs and grasses, while the adults more often frequent hardwood tree species. Excess sap becomes concentrated as honeydew, which often attracts ants. Some species have a well-developed ant mutualism, and these species are normally gregarious as well, which attracts more ants.

The largest Arthropleura may have been the biggest bugs to ever live, although there is still a debate. They may be a close second to an extinct giant sea scorpion. Researchers in Europe and North America have been collecting fragments and footprints of the huge bugs since the late 1800s.
Trombidiidae, also known as red velvet mites, true velvet mites, [2] or rain bugs, are small arachnids (eight-legged arthropods) found in plant litter and are known for their bright red color. While adults are typically no more than 4 mm (0.16 in) in length, some species can grow larger and the largest, including the African Dinothrombium ...
Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from 0.5 to 1.0 mm (0.020 to 0.039 in) long. They include the world's smallest known insect , with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect , only 0.15 mm (0.0059 in) long.
A year later, he dug up the blocks and found that most of the toads were dead and decayed. A few toads that had been in the porous limestone were still living, but the glass had developed cracks which Buckland believed may have admitted small insects. However, Buckland found them all dead after reburying them in the limestone for another year.
