Shards of the coralline Mastophora pacifica were collected from Redcliffe, Queensland (27[degrees]14'S; 153[degrees]6'E), and transported to Heron Island for use as a positive control.
The FSW negative control induced 0% metamorphosis by 48 hpi, while the positive control Mastophora pacifica (from Redcliffe, Queensland) induced a mean of 80% metamorphosis by 48 hpi, consistent with previous studies (Jackson et al, 2005).
Sexual mimicry in spiders has been reported only in interspecific interactions such as the bolas spider Mastophora
These species, including crab spiders in the genera Misumena, Misumenoides, and Misumenops that wait on flowers to catch visiting flies and bees (Kaston 1981; Nentwig and Wissel 1986) and certain specialized hunters that use lures but do not construct webs (e.g., araneids in the genus Mastophora that feed on moths; Yeargan 1988), are highly dimorphic.
In particular, protandry may be the optimal maturation strategy for males of most spider species, and strong selection for protandry may be the primary cause of extreme sexual size dimorphism in some species, such as those in the genus Mastophora. In other species, fecundity selection may produce initial sex differences in size and bring other selective factors into play.
Ecology of a bolas spider, Mastophora hutchinsoni: phenology, hunting tactics, and evidence for aggressive chemical mimicry.
A new species of the genus Mastophora is described from Argentina.
But the specimen of Mastophora Holmberg 1876, recently found from Argentina is exceptional in appearance, and I feel it should be described along with the male of M.
Mastophora adults live in trees, attached to a silken substrate, on branches or leaves sometimes on berries or leaf buds mimicking bird droppings.
