The family of a two-month-old baby who died in Perth after being bitten by a spider are trying to raise $20,000 to help cover the funeral costs.

Lance Ryder was airlifted from Geraldton to Perth after his parents found a spider bite on his hand. He died later that night.

The baby’s aunt Kathleen Nelly has now launched a crowdfunding appeal.

“Helping my big sister Mary out with tributes and memorial stone. Such a tragedy to hold your dying son in your arms.” Ms Nelly wrote on the website.
