Phylus melanocephalus
This record describes Phylus melanocephalus (species). Recorded family: Miridae. Recorded order: Hemiptera.
Identification and Appearance

Length 4.5-6 mm. Phylus bugs are fairly long and slender. There are three species in the UK, which can be separated with some reliability by the colour of the head and forewings. Host plant is also a useful aid to identification. The forewings of this species vary from yellow to orange-red but the head is usually dark brown or black. Specimens with a pale head were previously thought to be a separate species ( Phylus palliceps ) but have now been included within Phylus melanocephalus . This species can be identified with care but there are similar species that it could be confused with. No additional images available for this species.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Phylus melanocephalus. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
