Estas moscas conhecidas também como mosca-perna-de-pau têm o hábito de levantar as pernas na frente da cabeça para que elas sejam confundidas com as longas antenas das formigas e algumas espécies tendem a serem confundidas com vespas.

Unknown insect? These were on a tree where the bark had been peeled off. There were several ants on and around them.

On Cirsium drummondii which was blooming. The fly has three perpendicular lines forming a rectangle, generally pale brown. Flying much earlier than late-July to late-August reported for T. palposa in Ontario (Jackson, M.D., Marshall, S.A., Hanner, R. and Norrbom, A.L. 2011. The Fruit Flies (Tephritidae) of Ontario. Canadian Journal of Arthropod Identification No. 15, May 24 2011, available online at doi: 10.3752/cjai.2011.15), but T. occidentalis hasn't been reported east of ~B.C., Canada on Natureserve (https://explorer.natureserve.org/Taxon/ELEMENT_GLOBAL.2.896257/Terellia_occidentalis). Appears to be more consistent with T. occidentalis, but perhaps a specialist can help! There were two individuals of this species on the thistle.
Study in partnership with stewards at Sylvan Dale Community Pasture (Association of Manitoba Community Pastures).
