Table 6 Priors for calibrating phylogenies in BEAST

Analysis	Taxon	Distribution	Calibration type	Priors
Diptera phylogeny	Schizophora	Lognormal	Fossil [50, 52]	Mean = 3 St. dev. = 0.78 Offset = 70
Diptera phylogeny	Chloropidae	Lognormal	Fossil [52]	Mean = 3 St. dev = 0.7 Offset = 42
Simplified Diptera Phylogeny	Chloropidae	Normal	Posterior distribution from Diptera phylogeny	Mean = 59.41 St.dev. = 8.9
	Incertella incerta	Normal	Posterior distribution from Diptera phylogeny	Mean = 31.93 St.dev = 11.54
	Meromyza columbi	Normal	Posterior distribution from Diptera phylogeny	Mean = 23.48 St.dev = 10.3
	Trixoscelis fumipennis	Normal	Posterior distribution from Diptera phylogeny	Mean = 29.3 St.dev = 13.14
Demography	Incertella incerta	Normal	Tmrca from simplified phylogeny	Mean = 1.788 St.dev = 0.63 μ = 0.0042661
	Meromyza columbi	Normal	Tmrca from simplified phylogeny	Mean = 1.32 St.dev = 0.47 μ = 0.0023813
	Trixoscelis fumipennis	Normal	Tmrca from simplified phylogeny	Mean = 2.23 St.dev = 0.64 μ = 0.0027401

Tmrca is the time to most recent common ancestor (in Myr) and μ is the mutation rate (in mutations per site per million year)
