With the black leatherleaf slug having such a voracious and scavenging appetite, they could establish in urban, suburban and rural areas. As the common name suggest, this slug is typically jet black with an inconspicuous tan stripe down the underside. This terrestrial slug is from the family Veronicellidae (leatherleaf slugs) andcan grow up to 3.5 inches in length. They have two ocular tentacles that are also black. While they’re not parasites themselves, they have the ability to transmit harmful nematodes (Angiostrongylus cantonensis) to mammals including humans. Distributi… It was found in South Carolina in 2007, and an Oklahoma greenhouse in 2011. Over 2017-2020 the known distribution has expanded in Texas, thanks to diligent citizens reporting and mailing in specimens to the Texas Invasive Species Institute. ** After handling live slugs, hands should be washed in hot soapy water, and rinsed in alcohol or a standard hand disinfectant. There is a pale, inconspicuous tan stripe down the center of the back, which may not be visible. “Simply washing any garden vegetables before consumption would prevent any parasite transmission to humans,” Morgan-Olvera said. The New Guinea flatworm may be tiny, but it can carry a dangerous parasite. Copyright 2020 by KSAT - All rights reserved.

In Honduras, where it is also invasive, it was reported as an important vector of the nematode parasite Angiostrongylus costaricensis that causes abdominal angiostrongyliasis in humans. If you think you found one, but need confirmation about the species, you can send pictures by email to Morgan-Olvera at arm001@shsu.edu. (Photo: © T.W.

In fact, this writer spotted some last weekend. Researchers say the slugs are well-established in the San Antonio area. Ideally, we would be able to pick up specimens reported to us, but sometimes it isn't feasible. The underside of the worm is a pale tan color and the upper-side has a faint stripe. Young slugs are not as dark, and their underside is much lighter.

The Black Velvet Leatherleaf Slug is an invasive species in Texas and can carry the nematode parasite Angiostrongylus costaricensis that causes abdominal angiostrongyliasis in humans. American Malacological Bulletin, 27(1/2), 113-132. She came to KSAT as a news producer in 2000. The dorsal surface of the mantle may appear velvety or wrinkled. Angiostrongylus is commonly referred to as rat lungworm. If you need help with the Public File, call 210-351-1241. The velvety/wrinkled mantle covers the entire length of the body. REQUEST FOR SPECIMENS OF THE “BLACK VELVET LEATHERLEAF SLUG” The “Black velvet leatherleaf slug”, Belocaulus angustipes (Heynemann 1885), has now been reported from all five Gulf Coast states, and as of 2007 is confirmed for southeastern South Carolina. It’s a known predator of earthworms and may feed on other live organisms. Thome, modified by K. Weigel, University of Florida), Belocaulus angustipes: genitalia-pedal gland. Although abdominal angiostrongyliasis is not yet reported in the region where the slug has been detected, it is recommended that latex gloves be worn, or at least samples handled using a plastic bag**.
Just a plain black slug: Belocaulus angustipes. Reach out to her for more information on how to do that. It is also known to be an intermediate host for the nematode Angiostrongylus costaricensis, causative agent of the rat lung disease, oesinophilic meningoencephalitis. The black velvet leatherleaf slug doesn't closely resemble any native terrestrial slugs. Since then they’ve been seen throughout the Southeastern United States. Thome, modified by K. Weigel, University of Florida), Belocaulus angustipes: genitalia-penial gland. So I reached out to The Texas Invasive Species Institute and sent some pictures for confirmation. This is why we tell every citizen who contacts us (or looks at the species page on our website) not to bare handle any flatworms and to always wash your hands with soap and water afterward,” Morgan-Olvera said. U.S. Habitat: Since they are intolerant of low humidity the sup-tropical southeastern United State are very suitable.

2009. Specimens were found in an Oklahoma greenhouse in 2011. Thankfully, it has not been confirmed to vector this nematode in the states it is present. There is a pale, inconspicuous tan stripe down the center of the back, which may not be visible. It can inhabit greenhouses, grassy fields and nurseries. “This is the New Guinea flatworm (Platydemus manokwari) which is a fairly recent invader in Texas,” I was told. It is jet black in color with similarly colored tentacles. Belocaulus angustipes: note wrinkled appearance of mantle. This nocturnal pest species consumes a wide variety of plants. “The correct host for these nematodes are rats, but they’ll try to get into any mammal- they’re just not able to complete their lifecycle inside other non-rat hosts,” said Ashley Morgan-Olvera, director of research and education/outreach for the Texas Invasive Species Institute. Here in Texas, they’ve been spotted throughout San Antonio, Corpus Christi, Austin, College Station and the greater Houston area.

Frank, Jacksonville), Belocaulus angustipes: adult with eggs. U.S. Habitat: Since they are intolerant of low humidity the sup-tropical southeastern United State are very suitable. Thankfully, transmission of the parasite is easily prevented. “For humans in developed countries, it can happen after we handle the flatworm/slug and then touch our mouths. After producing thousands of newscasts, she transitioned to the digital team in 2015. I remembered reading about an invasive type of worm, and when my preschooler pointed out the unusual black worms on our back porch after a rain storm, I knew they weren’t typical earthworms. After being misidentified as Vermicella ameghini, in 1989 it was suggested to be Belocaulus angustipes, and was decisively confirmed in 2009. According to the Centers for Disease Control and Prevention, Angiostrongylus usually causes mild symptoms in humans but can lead to a rare type of meningitis (eosinophilic meningitis) with symptoms including headache, stiff neck, tingling or painful feelings in the skin, low-grade fever, nausea and vomiting.

SAN ANTONIO – An invasive flatworm has made its way into Texas and has been found throughout the San Antonio area, experts say. Please click here and read and follow instructions if you have found a specimen near you. The pneumostome (breathing pore) and anus is located posteriorly. The parasite is transmitted to mammals when they ingest an infected flatworm or slug. (Photo: © B. Frank, Jacksonville), Belocaulus angustipes.
If you can preserve it in a container with isopropyl or ethanol alcohol like vodka, rum or Everclear, she’s also accepting specimens.
The mantle extends over the entire length of the body.

Belocaulus angustipes was first collected in Mobile, Alabama in August of 1960; then in New Orleans shortly thereafter. Both ends look similar, but the end with the head is narrower and has two eyespots. The worms range in size from 1.6 to 2.6 inches. (Photo: © T.W. (Photo: © B. Frank, Jacksonville), Belocaulus angustipes: note black flecks on the ventral of the mantle. Both the breathing pore (pneumostome) and anus are located posteriorly. They tend to live underneath living or inanimate objects such as fallen trees, planks and garden pots. Click here to read more about the New Guinea flatworm on the TISI site. According to the Texas Invasive Species Institute, the tiny black worms made their way into the United States and were first spotted in Florida in 2015. Photographer: Dr. Matthew McClure A., & Graeff-Teixeira, C. (1997). The flatworms are predators of native snails and other invertebrates. It is jet black in color with similarly colored tentacles. It is commonly found in St. Augustine grass. (Photo: © T.W. (Photo: © B. Frank, Jacksonville), Belocaulus angustipes: genitalia-penis in two positions. The Nautilus 75(2): 79-83. Commonly found in St. Augustine grass, they can also be found under rocks, boards, flower pots, greenhouses and even in the hearts of plants such as lettuce or cabbage. In addition to the New Guinea flatworm, TISI also warned of another invasive species that can carry rat lungworm -- the Black Velvet Leatherleaf slug. This slug can measure up to 55 mm when fully extended. The foot appears tripartite because the mantle of this species has black flecks along the margins. Belocaulus angustipes (Heynemann, 1885) B lack-velvet Leatherleaf: U. S. Department of Agriculture request for specimens : This invasive species was initially found in northeast Florida under a small piece of wood near a retention pond/lake at Baker Skinner Park in southern Duval County, Florida on 7/12/2005 (number 1 on the map).
