Description
Length: Male 6 to 9.5 mm, Female 6.8 to 10 mm. This group of flies, sometimes called Dance flies, are predators of other insects, often tackling large prey, using their long, dagger-like snout. This species is distinguished from the very similar Empis tessellata by having red/brown thighs (E. tessellata has black thighs).
Habitat
Along hedgerows where it takes other insects and nectars on flowers.
When to see it
April and May.
Life History
Males of E. opaca and E. tessellata present a ‘gift’ to the female, in the form of a dead insect, before mating takes place. Females will not mate with males who do not present a gift.
