Opomyza florum

    Description

    A small (5 to 5.5 mm) orange coloured species with black wing markings. It is slow moving and sometimes reluctant to fly.

    Habitat

    Meadows, fields of cereal crops and water margins.

    When to see it

    Flies hatch in June and July, and will be found in grassland and well wooded areas until late August, then they start to move to cereal fields where they can be found until the end of October.

    Life History

    Larva feed on the stems of grasses and can be a pest of cereals. Especially common in early sown wheat crops by late September and October, where they lay their eggs at the base of the plants. As the larva feeds on the stem's interior tissues this results in stunted growth and in high population times this can cause significant cereal crop damage.
