Taken near Humbie, Scotland. Generic name from Greek “Erio” meaning wool and “zona” meaning belt - a pretty apt description. Large attractive bumblebee mimic first recorded in Britain in 1968 and is probably a recent colonist. Larval food appears to be aphids on spruce trees so has no doubt benefitted from the widespread use of spruce in upland conifer plantations.
Beetle flies (Celyphidae) are small to medium-sized and easily recognised. The scutellum is enlarged, forming a protective shell over the abdomen, giving them a beetle-like appearance. Also, like many beetles, Celyphidae are often shiny or metallic in colour. The wings, when at rest, are folded beneath the scutellar “shell” . About 90 species are known from the Oriental and Afrotropic biogeographic regions; Spaniocelyphus palmi is probably the commonest celyphid species in the Oriental region [PAPP et al., 2006: p.186f]. The biology of the family is poorly known. Adults are found along streams and rivers, and in wet grassy areas. Larvae are saprophagous [WORLDLINGO] in decaying plant matter, likely feeding on associated micro-organisms [S.D Gaimari].
