The top picture provides one reason that thick-headed flies (Conopidae) are so named. Their heads are generally wider than their bodies.

They are also sometimes called wasp flies because their thin waist gives them a resemblance to wasps.

Most Conopidae species are, on average, larger than horse flies and smaller than wasps. They can often be found nectaring on flowers.
