Pet Insect: Though lacking economic value like butterflies and bees (which are collected as specimens or used to make honey), because the fly is numerous and harmless--it doesn't burn, bite, prick or sting (see "The Life of a Firefly") --it has become a beloved "pet insect."
由於數量眾多，螢光又不燙手，成蟲又不咬人、不刺人、不螫人（請參閱「螢火蟲的一生」），幾乎沒有攻擊性，因此螢火蟲不像蝴蝶、蜜蜂具有製成標本、生產蜂蜜等「經濟作用」，也不致被大量捕捉，而成了人們最愛的「寵物昆蟲」。
