Rhynchitidae

The tooth-nosed snout weevils, Rhynchitidae, are small beetles (1.5 to 6.5 mm) that are usually found vegetation. They usually use buds, fruits, or seeds for oviposition. The tooth-nosed snout weevils receive this name due to the teeth on the edges of their mandibles.

Rhynchitidae (disputed)

Traditionally considered a subfamily of Attelabidae within the Curculionoidea (weevils and relatives), the tooth-nosed snout weevils are regarded as a separate family Rhynchitidae by some authorities.

A common member of this group is the rose curculio, Merhynchites bicolor, which feeds on roses.

A number of species from Rhynchitidae are recorded from Britain.

The thief weevil, Pterocolus ovatus, is the only pterocoline (subfamily Pterocolinae) known from North America. It is an obligate egg predator and nidus kleptoparasite (nest thief) of some beetles in the family Attelabidae.

gollark: I am hoping that whoever is behind that won't decide to try something like this again, but I bet *someone* will think "ah yes, this is a great idea, we'll just lie because it's mildly more convenient, that can't go wrong in the long term".
gollark: ... yes, that.
gollark: It probably doesn't help that apparently some people said they were unhelpful in order to ensure that healthcare people had enough.
gollark: There was a lot of confusion about this initially but the consensus seems to have converged on them being useful.
gollark: No, they aren't.
