Lamprolonchaea
Bezzi, 1920
metallic-green tomato flies, lance flies
Species Guides
1Lamprolonchaea is a of lance flies (Diptera: Lonchaeidae) characterized by bright metallic golden-green coloration. The genus includes at least 24 in Australia, with Lamprolonchaea brouniana being the most economically significant as a pest of tomato fruit. Australian species are taxonomically poorly understood, with limited descriptions of stages and no prior molecular characterization. The genus appears to be restricted to Australia, with most records from temperate southern regions.

Identification
Bright metallic golden-green coloration distinguishes from other Lonchaeidae. -level identification requires examination of adult morphological characters; a key to Australian species is available. Larvae are sometimes confused with tephritid fruit fly larvae in food produce, requiring detailed morphological examination or COI barcoding for accurate identification.
Habitat
Temperate regions of southern Australia; associated with fruit-bearing plants.
Distribution
Australia; most commonly collected from the temperate south. to Australia based on current records.
Seasonality
and larval activity occurs during warmer summer and autumn months.
Host Associations
- tomato fruit - larval primary for L. brouniana, >70% of records
- various fruit - larval secondary across multiple plant
Life Cycle
Larval stage is the most commonly encountered life stage, found in food produce. and patterns have been observed but detailed staging requires further study.
Behavior
Larvae are not normally found in association with other serious primary pests such as Queensland Fruit Fly (Bactrocera tryoni), suggesting limited competitive or commensal interactions.
Ecological Role
Agricultural pest; larvae develop in fruit, causing direct damage to produce.
Human Relevance
Economic pest of tomato and other fruit crops. Larvae in produce are sometimes misidentified as tephritid fruit flies, complicating and pest management decisions. COI barcoding now available to enable accurate from larvae.
Similar Taxa
- Tephritidae (fruit flies)Larvae are morphologically similar and frequently confused; both groups infest fruit and are encountered in food produce.
- other LonchaeidaeNon-metallic lack the distinctive golden-green coloration of Lamprolonchaea .
Misconceptions
The 'metallic-green tomato fly' is applied to multiple similar bright metallic golden-green lance fly , not solely to Lamprolonchaea brouniana.
