Hoverflies (Syrphidae), tribe Eristalini

Moderate to large hoverflies, bee or bumble-bee like (this page are rather more wasp-like). Larvae live in organic rich water.

Helophilus pendulus (Linnaeus, 1758)

Helophilus pendulus
  • Cambridge: 14 Apr 2002
  • By far the commonest UK species of Helophilus, which are distinguished by the yellow striped thorax.
  • Hind tibiae yellow on basal two-thirds (better seen here on the left leg)
  • Black stripe on face, (not visible from this angle)
  • Larvae filter food from drains & manure

Helophilus trivittatus (Fabricius, 1805)

Helophilus trivittatus
  • Cambridge: 14 Jun 2002
  • Noticeably larger and brighter than H. pendulus: rear abdominal segements are proportionally longer too.
  • No black stripe on face but may be some reddish-brown

Myathropa florea (Linnaeus, 1758)

Myathropa florea
  • Cambridge: 29 Jun 2002
  • Thorax black partly bisected with pale bars. Nothing else really like this in the UK.
  • 9mm long.
  • Larvae live in rotting wood, filtering food.
  • Myathropa appears to be an earlier spelling than the variant Myiatropa
