Video S1: Oviposition in Anchylorhynchus eriospathae
A female of Anchylorhynchus eriospathae laying an egg on a female flower of Butia eriospatha during male anthesis (B. eriospatha) is protandrous. Notice that the female does not drill with the rostrum and instead lays the egg between the bracts that surround the flower.
Video S2: Cannibalism among first-instar larvae of Anchylorhynchus eriospathae
We removed two first-instar larvae of Anchylorhynchus eriospathae and placed them in Petri dishes for better visualization. Here a larva consumes another that was recently attacked and still moves its mandibles.
Video S3: Second-instar larva of Anchylorhynchus eriospathae feeding on first-instar larva
The first-instar larva was offered to a second-instar larva immediately after we opened the fruit. This video shows the bigger larva consuming the smaller one after killing it.
