Margined blister beetle larvae and adults produce cantharidin, a potent toxin causing skin irritation upon contact. Ingesting or touching margined blister beetle might lead to symptoms ranging from mild to severe, including blisters and gastrointestinal distress. Severe cases may involve complications like renal damage.

Margined blister beetle has a mild venom that it delivers through a sting, primarily as a defense mechanism. Adult organisms of this species can sting when they feel threatened. Humans may experience pain and irritation when stung, but the effects are generally minimal and not life-threatening. Similarly, pets and smaller mammals might show discomfort and localized reactions upon being stung. Even smaller arthropods can be affected, potentially leading to more serious consequences for them due to the relative potency of the venom compared to their body size.

Margined blister beetle has the potential to trigger allergic reactions in a small subset of individuals through contact, especially in its adult stage. Exposure to its toxins can result in symptoms ranging from mild to severe. The degree of risk varies amongst people, and those with sensitivities should avoid handling margined blister beetle.

The margined blister beetle secretes a potent toxin known as cantharidin, which can cause skin irritation when there is contact. Due to their crawling and flying habits, they may land on human skin or be inadvertently handled, leading to a range of reactions from mild skin irritations to more severe physical symptoms, including blisters.

To prevent the issues caused by margined blister beetle, avoid direct contact and maintain a clean environment to limit their presence. Use screens on windows and doors, wear protective clothing when handling materials where margined blister beetle could inhabit, and regularly inspect and clean spaces where they could potentially congregate.

If trouble with margined blister beetle arises, immediately wash the affected area with soap and water to minimize absorption of toxins. Cleanse any items that may have come into contact with margined blister beetle. Distract oneself from discomfort with cool compresses or baths. During recovery, avoid further contact with margined blister beetle and refrain from scratching affected areas to prevent secondary infections. Keep surroundings clean and monitor for any escalation of symptoms that might require professional advice.

Margined blister beetle larvae cause mild to severe damage by chewing on leaves, stems, flowers, and fruits of crops like potatoes, tomatoes, and corn. Infestation may lead to defoliation, reduced yield, and compromised plant health. In large numbers, they can significantly impact agricultural productivity and subsequently affect food supply.

Margined blister beetle, at both larval and adult stages, attacks plant leaves, flowers, and fruits by chewing tissues and sucking fluids, leading to a range of mild to severe plant damage.
