American Hover Fly on Thistle
by Timm on Jul.13, 2009, under Bugs, Flowers
Here’s a neat shot of what appears to be an American Hover Fly on a thistle flower. This fly gets its name from how it hovers above flowers. It’s considered a beneficial species because its larvae helps eliminate species that attack commercial crops and ornamental plants.
Thistle are very pretty but also invasive. They are armed with sharp thorns that are very painful. We have to clear them from our wildflower field every couple of years so they don’t take over.
