Additionally 1702 insect species (28% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 3 ]
The heaviest of this widespread, varied complex of insects is the Little Barrier Island giant weta, Deinacrida heteracantha, of New Zealand; one specimen weighed 71 g (2.5 oz) and measured nearly 10 cm (3.9 in), [2] giving it one of the largest insect weights ever known. These heavyweight insects can be over 9 cm (3.5 in) long. [8]

They are the largest insects in the order Hemiptera. [1]
[11] [16] Like most insects, communication within the species is a mix of chemoreception, sight, and mechanical perception. Experiments on D. hercules have shown that a male placed in the vicinity of a female will immediately orient towards her and seek her out, suggesting chemical communication through strong sexual pheromones.
The Tennessee Invasive Plant Council has identified the following invasive plants in Tennessee. The plants are all widely established across the state and have been reported in more than 10 counties.
The scale insect Dactylopius coccus produces the brilliant red-coloured carminic acid to deter predators. Up to 100,000 scale insects need to be collected and processed to make a kilogram (2.2 lbs) of cochineal dye. [89] A similar number of lac bugs are needed to make a kilogram of shellac, a brush-on colourant and wood finish. [90]
