Explanation of Names
Syritta pipiens (Linnaeus 1758)
6.5-9.5 mm(1)
Apical third of metafemur in both sexes with a row of spines along the ventral edge (photo); another good field mark is the pair of pale wedge-shaped spots on anterior margin of thorax behind the head.
Male: metafemur strongly thickened, but hardly bent, basally without protuberance; tergite 2-3 with small, pale spots. Female: Ocellar triangle black or bluish, metallic shining; thoracic dorsum dusted along side margin; tergite 4: side and hind margins not dusted. [Mark van Veen]
[From comment here: Syritta pipiens has two small white spots on the thorax directly behind head. And the hind tibia almost always has a red mark...and usually the hind femora too. Also the hind metatarsus is stubby and swollen.]
Across NA & Eurasia(2)
Larvae in wet decaying organic matter (manure, compost, silage)(1).
Stages of Syritta pipiens have been reported from cow and horse manure, from guinea pig manure and from human excrement. It has also been found in decayed and rotting tulip bulbs and in heaps of vegetable refuse (Hodson, 1931).
mid-Apr to mid-Oct in ON(1)
Larvae feed on decaying Narcissus bulbs; wet manure, compost and silage.
Introduced from Europe in the 1800s (Martin Hauser's comment).
