From Wikipedia:
Lonchaeidae is a family of acalyptrate flies commonly known as lance flies. There are about 500 described species in 9 genera. These are generally small but robustly built flies with blue-black or metallic bodies. They are found, mainly in wooded areas, throughout the world with the exception of polar regions and New Zealand.
The larvae are mostly phytophagous, feeding on already damaged plant tissues, although coprophagous, mycophagous, saprophagous and predatory species are known.
