Tribe Eristalini
Moderate to large hoverflies, bee or bumble-bee like.
Syrphidae with complete longitudinal stripes on the thorax belong to this tribe. Of the striped flies, those with a broadly darkened area where a vein meets the wing margin near the middle of the wing belong to Helophilus while those with a narrow crossvein-like dark spot belong to Parhelophilus or Lejops.(1)
Larvae live in organic rich water.
