Tunga penetrans is a species of flea also known as the jigger, jigger flea, chigoe, chigo, chigoe flea, chigo flea, nigua, sand flea, or burrowing flea. It is a parasitic insect found in most tropical and sub-tropical climates. In its parasitic phase it has significant impact on its hosts, which include humans and certain other mammalian species.
The preponderance of tungiasis lesions on the toes may be because chigoe flea is a poor jumper, attaining only a height of 20 cm. [14] But the reality is more complex; for example, the jumping ability cannot explain why hands are the second-most affected body part. Lesions on the hands are better explained by playing in the sand and noting that ...
Chiggers are often confused with jiggers – a type of flea. Several species of Trombiculidae in their larva stage bite their animal host and by embedding their mouthparts into the skin cause "intense irritation", [4] or "a wheal, usually with severe itching and dermatitis". [5] [6] [7] Humans are possible hosts.

Jigging gears are often involved with the luring of slow moving fish, most commonly during spawning periods. For successful jigging, the jigger needs to use a sensitive rod that is good for feeling a strike, and needs to stay in contact with the lure and get it to where the fish are. Most fish caught by jigs are on or near the bottom.
Trombicula, known as chiggers, red bugs, scrub-itch mites, or berry bugs, are small arachnids [2] (eight-legged arthropods) in the Trombiculidae family. In their larval stage, they attach to various animals and humans, then feed on skin, often causing itching and trombiculosis. [3]
Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of 1–2 mm in size, on the palms of the hands, sides of fingers, or bottoms of the feet. [8] Outbreaks usually conclude within three to four weeks, but often recur.
