Tailless Whipscorpion

Hi Neighbor,
This is a harmless Tailless Whipscorpion, a shy predator that prefers the dark, hence its presence in the cave.  It is our understanding that Cancle is a common name used in some Spanish speaking countries for the Tailless Whipscorpion.

Your letter to the bugman:  I found this fellow happy and healthy on the kitchen floor amidst the corpses from a cockroach spraying.
From one tip to another the spread of the antennae is about 4 inches.
I’m having trouble looking him up online.   Any help would be greatfully received.

Tailless Whip Scorpion

Dear Frank,
This is a Tailless Whip Scorpion, and unlike its namesakes, the true Scorpions, it lacks venom, so it is no threat to humans, though a large individual might bite if carelessly handled.  Tailless Whip Scorpions are shy predators that hunt at night and they will help keep your home free from other more problematic creatures, like Cockroaches, Scorpions and Spiders.  Based on this BugGuide image, we believe your individual is Paraphrynus carolynae.  According to BugGuide:  “The very long front legs are referred to as ANTENNIFORM LEGS. The animal uses them to ‘feel’ its way about and to locate its insect prey, which is captured with the spiny pedipalps.”

Your letter to the bugman:  Not sure this is an insect.  The front appendages do seem to be pincers.  The overall length including the “tail” is over 8″!  Seen July 17, 2018.

Giant Vinegaroon

Dear Dave and Teri,
This is a Whipscorpion, Mastigoproctus giganteus, commonly called a Giant Vinegaroon or Grampus.  Though related to Scorpions, they are not considered dangerous as they lack venom, but they can secrete a weak acetic acid that smells like vinegar.  Giant Vinegaroons are shy, nocturnal predators with powerful mandibles, so they are capable of biting.  At the risk of being repetitive, according to BugGuide:  “The vinegaroon is nocturnal and has poor vision. The whiplike tail is used as a sensory organ, as is the first pair of legs, which is not used for walking. Although its tail in unable to sting, this creature can spray an acidic mist from a scent gland at the base of the tail when disturbed. The spray is 85% concentrated acetic acid/vinegar, hence the common name ‘Vinegaroon.’ The heavy pinching mouthparts (modified pedipalps) can also inflict a painful bite. Although very unlikely to attack humans, it can certainly defend itself if provoked.”

Whipscorpion

Dear Devin,
This is a Whipscorpion or Vinegaroon, a non-venomous, distant relative of Scorpions.  Whipscorpions are not considered dangerous to humans, but they do have strong mandibles, so they might bite if carelessly handled.  They are shy nocturnal predators that will help keep populations of Cockroaches under control.  Arachnoboards lists Mastigoproctus proscorpio as a Dominican species.
