However, recent genetic evidence strongly suggests that they evolved directly from 'true' cockroaches, and many authors now place them as an "epifamily" of Blattodea. [15] This evidence supported a hypothesis suggested in 1934 that termites are closely related to the wood-eating cockroaches (genus Cryptocercus ).
Mayfly phylogeny was further studied using morphological and molecular analyses by Ogden and others in 2009. They found that the Asian genus Siphluriscus was sister to all other mayflies. Some existing lineages such as Ephemeroidea, and families such as Ameletopsidae, were found not to be monophyletic, through convergence among nymphal features ...
The heaviest of this widespread, varied complex of insects is the Little Barrier Island giant weta, Deinacrida heteracantha, of New Zealand; one specimen weighed 71 g (2.5 oz) and measured nearly 10 cm (3.9 in), [2] giving it one of the largest insect weights ever known. These heavyweight insects can be over 9 cm (3.5 in) long. [8]
Lateral ocelli, however, are not found in all termites, absent in the families Hodotermitidae, Termopsidae, and Archotermopsidae. [63] [64] Like other insects, termites have a small tongue-shaped labrum and a clypeus; the clypeus is divided into a postclypeus and anteclypeus. Termite antennae have a number of functions such as the sensing of ...
[32] [52] Deserticolous millipedes, species evolved to live in the desert, like Orthoporus ornatus, may show adaptations like a waxy epicuticle and the ability of water uptake from unsaturated air. [53] Some species can survive freshwater floods and live submerged underwater for up to 11 months.
It is a small species of toad: males measure 16.5–23.5 mm (0.65–0.93 in) and females 20.4–30 mm (0.80–1.18 in) in snout–vent length.
However, new fossils found in 2007 and 2008 showed that the "chain mail" of tommotiids formed the tube of a sessile animal; one tommotiid resembled phoronids, which are close relatives or a subgroup of brachiopods, while the other tommotiid bore two symmetrical plates that might be an early form of brachiopod valves.
A flock of starlings reacting to a predator. Swarm intelligence (SI) is the collective behavior of decentralized, self-organized systems, natural or artificial. The concept is employed in work on artificial intelligence.
