BIONOMICS. Parker (1984) reported a nest of this species made in a side hole drilled in a pithy stem (the hole were slightly widened and lengthened by the female wasp). He also speculated that the species may nest in stone caverns. The described nest had a single cell sealed with the closing plug which “consisted of several large sand grains that were held in place by smaller pieces and liquid substance” (Parker, 1984: 524). Fateryga & Podunay (2018)

supposed that this liquid substance was actually nectar. Indeed, the described closing plug appears similar to that of Alastor (Alastor) mocsaryi (André, 1884) , a species which proved to use nectar for the nest construction ( Fateryga & Podunay, 2018). It was also speculated that the use of nectar is correlated with its robbing from the flowers by gnawing holes in the perianth ( Fateryga et al., 2020). Bohartodynerus cinnabarinus is a common nectar robber. It is known gnawing the holes in calyces of Astragalus holmgreniorum Barneby (Fabaceae)

(Barlow & Pavlik, 2017) and corollas of Penstemon sp. (Plantaginaceae) (Figs 21, 22). There is also a photo of apparently this species robbing nectar from a calyx tube of a flower of

Calylophus sp. (Onagraceae) . (https://www.inaturalist.org/observations/26950910).

Provision of B. cinnabarinus is lepidopteran caterpillars (Parker, 1984). Parker also reported that the cocoon of this species “was similar to that of O. erythrogaster (sand and silk)” (Parker, 1984: 523), which will be described below.
