What do aphids look like?
Aphids are small (1-4mm) parasitic insects which suck sap from young plant stems, leaf veins and flower buds. A few aphids might not do much harm but many will reduce a plants health to a point where leaves begin to twist and distort. Many aphids clustered on blooms will cause the bloom to not produce fruit. Aphids can also transmit virus diseases such as broad bean wilt. As aphids feed their excrement provides an environment for sooty mould to grow. Aphids can populate very quickly so prompt action is needed upon first signs of infestation.

Sciarid Flies are small (3-5mm) insects. The larvae are legless and translucent with dark, shiny heads. Larvae are usually found the surface layer of the growing medium so they can be difficult to find, although you may see them underneath leaves that are close to the media surface. Plants attacked by sciarid fly larvae are weakened and stunted. Young roots are eaten away. Larvae can mine into cuttings. Feeding damage creates entry points for root diseases such as Pythium. Adult flies have been shown to carry fungal spores.
