Necydalis sirexoides is closely related to Necydalis ulmi Chevrolat, 1838 and also both species develop in a very similar way. It means that the larvae feed on a highly fungi-rich substrate present inside hollow living deciduous trees. A paper dealing with larval nutrition and female oviposition preferences of some Necydalis species was written by Rejzek and Vlasák [❖].

Body length:15 - 30 mm
Life cycle:3 - 4 years [?]

Host plant:polyphagous on deciduous trees
Distribution:a species endemic to Iran

The depicted beetle, a female, was reared from a larva collected in a hollow living Carpinus in NE Iran, prov. Khorasan, Golestan forest 45 km NE Minudast.
