A 14-year-old boy tragically died after ‘injecting himself with a butterfly’ as part of an ‘online challenge.’

Davi Nunes Moreira, of Planalto, Brazil, reportedly suffered an agonising seven-day death in hospital.

The teenager is said to have originally told his father he had suffered an injury while playing.

However, as the boy’s symptoms worsened, he reportedly admitted to what he had done.

Despite receiving specialist treatment, Davi’s condition sadly worsened, and doctors were unable to save him.

An official cause of death has yet to be determined, however, the Civil Police of Bahia have launched an investigation into his passing.

A spokesperson stated: “The autopsy results will help clarify the cause of death.

“The investigation is designed to clear up what happened.”

The teen injected a solution from a crushed butterfly into his leg as part of a social media craze, according to local media.

It’s believed he began vomiting and started limping shortly after.

Davi reportedly admitted to injecting the solution after being admitted to the hospital.

He is said to have told medics that he went into a chemist to pick up supplies before mixing a dead butterfly in water and injecting the liquid into his leg.

Davi’s father reportedly found the syringe the teen used on himself under his pillow while tidying the house.

Doctor Luiz Fernando D. Relvastold told news site VivaBem that the teen’s death could have been the result of ‘an embolism, an infection, or an allergic reaction.’

“We don’t know how he prepared this mixture or the size of the fragments he managed to inject into the body,” the doctor added.

“There may have been air left inside, which could lead to an embolism.”

Investigators are reportedly looking into the possibility that Davi went into septic shock after the toxins from the mix caused his body to shut down.

Professor Marcelo Duarte, director of Sao Paulo University’s Zoology Museum and a butterfly specialist, said (per MailOnline): “Butterflies have a complex biology, and the fluids present in their bodies have not been studied in depth in terms of their toxicity to humans.”

Some Brazilian media outlets are openly speculating that Davi picked up on an experiment he saw online, however, the teen is said to have denied this allegation before his death.
