https://en.wikipedia.org/wiki/Bembix_rostrata Bembix rostrata forms colonies between a dozen and several hundred insects, where the females each construct a tube up to 20 cm long containing a single brood cell. This is stocked with dozens of insects, predominantly large flies (Tabanidae, Syrphidae), which provide the larva with food for its two-week development to the imago stage. The female carefully re-seals the nest tube after each feeding. Because of this intensive maternal care, a female can raise at most only eight larvae during the high summer. B. rostata is very faithful to its nest sites, often nesting in the same places year-on-year, even if these change over time and alternative habitats are available. The species has become rare due to loss of large open-sand surfaces in warm areas.
