Echidnophaga gallinacea


Echidnophaga gallinacea, commonly known as the hen flea, stickfast flea and sticktight flea, occurs on a wide range of bird and mammal hosts. If uncontrolled it causes anaemia, loss of condition, severe skin irritation and sometimes death.
When feeding, female fleas can remain attached for up to 6 weeks at a single site on the host, causing ulceration at the attachment site. Males feed intermittently while displaying mating behavior. Eggs are laid in the ulcers that have formed on the host's skin. The larvae drop to the ground and feed on any organic debris found. Large numbers of the flea may congregate around the eyes, comb, wattles, and other naked skin on poultry - these are difficult to dislodge as their heads are embedded deep below the host's skin.
In 2009, a female specimen of Echidnophaga gallinacea was found on the cheek of a 33-month old human male who lived with family across from Griffith Park in Los Angeles.
