The saw-edged antennae of moths, which give the long feelers a fuzzy look, are commonly used to identify them. Isabella Tiger Moth (Pyrrharctia isabella)įeathery antennae, nocturnal behavior, and the position of their wings while resting may be used to identify moths.Southern Flannel Moth (Megalopyge opercularis).Twin-spotted sphinx moth identification.Twin-Spotted Sphinx Moth (Smerinthus jamaicensis).Argent and Sable Black and White Moth (Rheumaptera hastata).Common Gray Moth (Anavitrinella pampinaria).Common Brown House Moth (Hofmannophila pseudospretella).White-striped black moth identification.White-Striped Black Moth (Trichodezia albovittata).Purple Thorn Moth (Selenia tetralunaria).Beautiful wood nymph moth identification.Beautiful Wood Nymph Moth (Eudryas grata).Blotched Emerald Moth (Comibaena bajularia).Types of Moths - Names, Pictures, and Identification Guide.Obliqua envenomation is Lonomia Antivenom (LAV). This makes all of the previously mentioned molecules good biomarkers in the clinical setting.Ĭurrently, the only known treatment for L. When certain RhoGTPases regulators (Rho GAP 21, Rho GEF 12) are modified by LOBE (L.Obliqua Bristle extract), this may cause activation Rac1 and cause an increase in cell membrane protrusion. Rac1 promotes or initiates actin assembly which is involved in cell to extracellular matrix adhesion and cell to cell adhesion. an important part of cell migration is coordinated by the Rho family GTPases. Obliqua venom seems to interfere with both which can influence cell migration and blood vessel permeability. There is evidence that supports that Obliqua venom has bioactive peptides that change the migratory characteristics of different cell types.Ĭell migration involves molecules on cells itself, and in the extracellular matrix, and L. Obliqua is thought to indirectly cause an up-regulation of several genes involved in the amplification and generation of the clinical manifestations listed above. By increasing intravascular thrombin ( a protein that causes blood clotting) concentration and disrupts endothelial cell monolayers, leading to hemorrhagic conditions and few leukocytes in test animals (5).L. Systemic vascular and inflammatory disorders can be stimulated by the venom of Lonomia Obliqua. Experimental findings have led researchers to believe that the venom released from Lonomia Obliqua larvae damages the blood-brain barrier. It is important to note that more severe cases of poison from Lonomia Obliqua have been studied in relatively recent times, and more surprising findings have come to light. Increase in fibrin degradation products.Burning sensation at the site of contactĪdditional clinical signs following skin contact.However, exposure does not cause a decrease in platelets as usually seen in coagulopathies. Clinically, fibrin degradation products increase, coagulation factor levels decrease, and clotting time increases. Giant silkworm larvae can release its toxins with anticoagulant properties through its bristles and if it comes into contact with the skin it can cause leukocytosis, anemia, bruising, hematuria, hematoma, vomiting, nausea, headache, a burning sensation at the site, swelling, redness, and pain. There has shown to be a higher incidence of accidents with Lonomia Obliqua in the spring and summer months, which is the time they are in the caterpillar stage, as stated earlier. Interactions with Lonomia Obliqua occur mostly through the skin on the upper limbs of children and rural workers. The earliest records of exposure to lepidopteran caterpillars date back to 1912 in Brazil and were described by Zoroastro Alvarenga. The larvae or caterpillar stage corresponds with the spring and summer months and this is of concern because this increases the chances of contact with humans.Įxposure to Giant silkworm moth larvae (caterpillars) and their bristles can cause a variety of symptoms ranging “from mild discomfort to systemic bleeding” (3). These hairs can cause skin irritation or sting. Lonomia Obliqua larvae are fairly large and rounded with tubercles and spines or hairs. Many species of this family have prominent eyespots and decorated with bright colors.ħ5 different species of Lonomia Obliqua live in North America north of Mexico and about 16 species live in Missouri including luna, imperial, rosy maple, royal moths, and more. These moths only live a few weeks because they do not feed as they have a little or absent mouthpart. A female’s antenna can be a feathery or a thin filament. They range in size from medium to very large moths, they have hairy, stubby bodies and feathery antennae. The giant silkworm moths are members of the Saturniidae family.
