When you eat a dried fig, you're probably chewing wasp mummies, too. of which just trust the wind to blow their pollen where it needs to go. It may be one of nature's oddest couples: a tiny wasp that can barely be seen, and a giant fig tree, the sycomore, which shelters a remarkable. Figs Without Wasps? Most commercial figs, like the ones you buy at the store, are grown without wasps.

You'll Never Be Able To Unlearn What Figs Are

Recent phylogenetic comparisons have supported this model of diversification for both insect herbivores and specialized pollinators. An exceptional case where contemporaneous plant—insect diversification might be expected is the obligate mutualism between fig trees Ficus species, Moraceae and their pollinating wasps Agaonidae, Hymenoptera. In particular, taxon sampling and analytical tools have been insufficient for large-scale cophylogenetic analyses. Here, we sampled nearly interacting pairs of fig and wasp species from across the globe.

Two supermatrices were assembled: We also developed a new analytical tool, Jane 2, for event-based phylogenetic reconciliation analysis of very large data sets. Separate Bayesian phylogenetic analyses for figs and fig wasps under relaxed molecular clock assumptions indicate Cretaceous diversification of crown groups and contemporaneous divergence for nearly half of all fig and pollinator lineages.

Event-based cophylogenetic analyses further support the codiversification hypothesis.

Are figs really full of baby wasps?

Biogeographic analyses indicate that the present-day distribution of fig and pollinator lineages is consistent with a Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance. Overall, our findings indicate that the fig-pollinator mutualism represents an extreme case among plant—insect interactions of coordinated dispersal and long-term codiversification. As primary consumers, most insect herbivores are involved in antagonistic interactions with plants and, although herbivores often exhibit host-specific coevolutionary adaptations to plant defenses Ehrlich and Ravenrecent empirical studies have suggested that host plant lineages are generally older than their associated herbivores Percy et al.

Such patterns of asynchronous plant—insect diversification are consistent with the general paradigm that insect speciation results from colonization of novel host plants and subsequent reproductive isolation Percy et al. Birds and insects often move pollen from flower to flower when gathering nectar and they are therefore called pollinators Would you be happy if your favorite fruit came with a prize inside, like some boxes of cereal?

What Is the Symbiotic Relationship between Fig Wasps & Figs? | Animals -

A young fig wasp female leaves the fig she was born in and searches for a fig in which to lay her eggs. A wasp finds a flowering fig by using her sense of smell. When she enters through the small opening, her wings and antennae are torn off.

A flowering fig is not easy to spot by sight. Unlike the bright, colorful flowers you see in a garden, fig tree flowers are hidden inside hollow balls that will ripen into figs.

Fig Wasps | Ask A Biologist

This means the fig wasp must use her sense of smell to find a tree with flowering figs. When she finds a fig with flowers, she squeezes through a tiny opening to get inside. The opening is so small that when climbing in, the wasp tears her wings and antennae.

This means that she will never be able to leave.
