And thanks yet once more, Paul!
I always think of this family in terms of bright yellow colours. ;)
Groetjes,
André

Siphonella oscinina (Fallén, 1820), Chloropidae. Nice photo as typical characters can be seen: densely haired eyes, narrow and protruding gena, long labellum of the proboscis, 3rd antennal segment lighter than basal ones, coarse (= rough structured) scutum, interfrontal setulae along the edge of the ocellar triange (and not on its surface). This species was abundantly trapped by M.v.T. in yellow colour dishes (only 14% in the same number of synchronous exposed yellow ones !) from mid of July to end of September on a bird island, North Sea, Germany. All such females were gravid with egg masses. The reason may be the search for white spider cocoons, produced by Araneae mainly from August onwards. Coquillett (1898, Bull. Bur. ent. U.S. Dep. Agric. (n.S.) 10: 70-79, p. 31) reared the species in North America from a spider cocoon and also Schwangard (1906, Z. wiss. Insektenbiol. 2: 105-107) reported such a case. The long proboscis speaks also for an association with spiders as several other Chloropidae with long probosci are commensals of spider meals. It is enigmatic that no spider experts since then ever published such rearing results.
