Striped blister beetle

Striped blister beetle

Epicauta vittata

A species of Burning blister beetles

Adorned with a sleek body, marked by distinctly contrasting stripes, striped blister beetle flourishes in environments rich with its preferred flora.

Habitat Preferences of Striped blister beetle Through Different Life Stages
The eggs of striped blister beetle are typically laid in the soil. Searching for larvae requires checking beneath the surface, as they are soil-dwelling and often found near their food sources, such as grasshopper eggs. For the mobile triungulin larvae, seek them on flowers or clinging to visiting bees, since they require a host for further development. Pupation again occurs in the soil, implying a need to excavate likely areas gently. Adults of striped blister beetle, on the other hand, can be found perched on flowers or vegetation, where they feed and mate.

When is the Best Time to Observe Striped blister beetle
The most suitable time to find striped blister beetle is during the daylight hours, particularly on sunny days when they are most active.

How and Where Can You Find Striped blister beetle at Different Life Stages
Larva Striped blister beetle larvae are parasitic and can be found inside or on their host species, such as grasshopper egg pods. Look for them by locating potential host species.
Pupal The pupal stage of striped blister beetle occurs in the soil or under the debris. To find striped blister beetle pupae, gently sift through the top layer of soil where larvae are known to be present.
Adult Adult striped blister beetle can be found on flowering plants. Look for them by observing such plants and gently inspecting flowers for the presence of striped blister beetle.

Are Striped blister beetle harmful to humans?

Striped blister beetle neither bites nor stings, and the cantharidin contained in it is highly toxic. Direct skin contact with striped blister beetle does not poison people.
It should be noted that when the striped blister beetle is frightened, it will secrete a small amount of cantharidin from the leg. The skin after contact will be red, swollen, painful, and burning, and blisters will appear within 48h. After waking up, many people will be confused by the blisters that somehow grew out of. Fortunately, the blisters caused by the striped blister beetle are temporary. Most people's symptoms will disappear within a week, and most of the recovered skin will not leave unsightly scars.

Toxic to Humans

Striped blister beetle is known to harbor potent blistering agents, particularly cantharidin, in both larvae and adult forms. Defense mechanisms of striped blister beetle encompass releasing these toxins upon touch, which can cause skin irritation or blistering. Ingestion can lead to more severe symptoms including burns, systemic toxicity, and renal damage. The effects range from mild skin reactions to potential long-term complications, depending on exposure level and duration.

Rectangle
Toxic to Animals

Striped blister beetle typically delivers its mild toxin via a sting, which can result in discomfort or a mild reaction. Adult specimens possess this ability and may use it when feeling threatened. Humans and pets such as dogs and cats might experience pain, redness, or slight swelling at the sting site. Animals like birds can also be affected by the toxin, showing similar mild symptoms. Among insects, the response to the toxin may be more pronounced due to their smaller size and different physiology, leading to potentially more serious consequences.

Does the Striped blister beetle cause allergies?

Striped blister beetle can cause allergic reactions in humans during its larvae and adult stages due to contact with the skin. Affected individuals, although few, may experience symptoms ranging from mild to severe. The allergies are triggered by toxins which lead to various reactions. People handling striped blister beetle should be cautious, and those with sensitivity may need to avoid exposure to minimize risk.
