我於我台中市東勢區山上的大自然觀察 My nature observations here in my hills of Dongshi, Taichung (Taizhong), Taiwan
人可近此蠅無幾公分， 故於都市應早已滅。 舌橘色亦大又一直搖。 翅圖似蝙蝠俠設計。 我一年遇之僅一二次。 蠅頭至尾長約三公分。
I could get centimeters away from this big fly (about 3 cm. head to tail) who does not fear people. I assume in cities you will never see it as it would have long been swatted into oblivion. It has a large orange tongue that it is constantly waving around. It has batman-designed wing coloring. I only run into this fly a couple times a year.
More photos: 白屁股 white butt, 舌 tongue, from 45 deg.
感謝 Thanks "Young, Chen" YoungC at CarnegieMuseums.Org for getting me started with Pyrgotidae. 進一步比對得名： Further comparisons on the net reveal it is: Loxonevra perilampoides or decora or ... (Platystomatidae.)
