Large flying insect about the size of a half dollar, yellow and black striped end with black hairs but no stinger, tongue looks like a fly, large eyes. Does not make a sound when it flies. Has been flying around us on our back deck for days.
Tachinid fly – Belvosia borealis
Your photo is of a fly called Belvosia borealis. It does not have a common name that I could find. In fact there is not a lot of information on this fly…especially for as large and colorful as it is!! These flies lay eggs on the host plants of their larval prey. The when the larva feeds on the plant it eats the eggs along with the plants. The fly larvae then grow and pupate inside the larval host, which is eventually killed. Could not find out what larva this fly feeds on, but perhaps you have some larva that it likes near your deck?!
It will not hurt you. < Moni has an ebook “Garden Insect Pests of North America – Pictures for Identifying and Organic Controls” Check it out!
