A diagram of the stylostome, or the hardened tube of dead cells formed by the larval form of the Trombiculidae when feeding. Chiggers attach to the host, pierce the skin, inject enzymes into the bite wound that digest cellular contents, [23] and then suck up the digested tissue through a tube formed by hardened skin cells called a stylostome.

A venomous spider bite (like this brown recluse bite) can cause a red or purplish rash radiating from the site of the bite. There are only a few species of spiders in the U.S. that can bite humans.
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]
Native plants and animals in Florida are threatened by the spread of invasive species. [2] Florida is a major biodiversity hotspot in North America and the hospitable sub-tropical climate has also become a hotspot for invasive plants and animals due to anthropogenic introduction. [3] [4]
Jerusalem crickets (or potato bugs) [1] are a group of large, flightless insects in the genera Ammopelmatus and Stenopelmatus, together comprising the tribe Stenopelmatini. The former genus is native to the western United States and parts of Mexico , while the latter genus is from Central America .
Unlike the Hemiptera (true bugs), the right mandible of thrips is reduced and vestigial – and in some species completely absent. [15] The left mandible is used briefly to cut into the food plant; saliva is injected and the maxillary stylets, which form a tube, are then inserted and the semi-digested food pumped from ruptured cells.
Euthyrhynchus floridanus, the Florida predatory stink bug, is a species of carnivorous shield bug in the family Pentatomidae, the only species in the genus Euthyrhynchus. It is native to the hottest parts of the southeastern United States and is considered beneficial because its diet includes many species of pest insects.
They are back “after an absence of 35 years,” officials say.
