Biology of the Carrion Beetle Silpha ramosa Say12

The Life History of the Japanese Carrion Beetle Ptomascopus Morio and the Origins of Parental Care in Nicrophorus (Coleoptera, Silphidae, Nicrophorini)

“…The brood size, reduced fecundity, and shorter larval developmental times are similar to those reported in Nicrophorus, but otherwise the life cycle characteristics are generally similar to those reported for the carrion-feeding Silphini (Balduff, 1935;Brewer and Bacon, 1975;Cole, 1942;Cooley, 1917;and Ratcliffe, 1972 …”

Biology and population development ofAblattaria arenaria [Coleoptera: Silphidae], a snail predator

“…The head and abdomen would be drawn forward almost touching and then moved back in the opposite direction. The main purpose of these motions was reported to prepare a pupal cell and was very similar to that described for Silpha ramosa (Brewer & Bacon, 1975) and in 10 another silphid species (Balduf, 1935).…”

“…The egg stage lasted 9.8 _+ 0.4 days (n = 87) without any mortality. The shorter duration of the egg stage of a related species, A. laevigata and of another silphid, Silpha ramosa Say, was reported as 5.8 and 5 days, respectively (Balduf, 1935 ;Brewer & Bacon, 1975).…”

Laboratory Rearing of Forensic Insects

“…The larvae undergo three stages, or instars, which are completed in about 22 to 26 days (Brewer and Bacon, 1975). Once the larval stages are complete, the larvae leave the carcass and crawl into the surrounding soil to pupate.…”
