1. Understanding Black Flies: Identification and Impact
What are black flies and why are they harmful to plants?
Black flies, also known as blackflies or buffalo gnats, are small, blood-sucking insects of the family Simuliidae. Unlike aphids, which are also called blackflies and are plant pests, the black flies we are discussing here primarily affect humans and animals by biting, not plants. However, confusion can arise because the term “blackfly” is sometimes used colloquially to refer to plant-infesting aphids, like the black bean aphid. This article focuses on clearing that confusion and discussing both types of “black flies.”
Aphids (Plant Pests)
- Identification: Black bean aphids (Aphis fabae) are small, black insects that colonize the stems and undersides of leaves, particularly on new growth. Cherry blackflies also target cherry trees specifically.
- Impact on Plants: These aphids suck sap from plants, weakening them, causing stunted growth, and distorting leaves. They also secrete honeydew, which can lead to sooty mold growth. According to research from the Royal Horticultural Society (RHS), heavy infestations can severely impact plant vigor and yield.
Simuliidae (Biting Insects)
-
Identification: These are tiny, dark, biting flies typically found near flowing water, where they breed. They are known for their irritating bites.
-
Impact on Humans and Animals: Black fly bites can cause itching, swelling, and discomfort. In some individuals, bites can lead to allergic reactions.
-
Life Cycle and Behavior:
- Aphids: Aphids have a complex life cycle, often involving both sexual and asexual reproduction. They can rapidly multiply, leading to quick infestations.
- Simuliidae: Black flies lay their eggs in flowing water. The larvae attach to submerged rocks or vegetation, and adults emerge to seek blood meals. According to a study by the University of Minnesota Extension, black flies are most active during daylight hours.
