  • 14 December 1979
Even when blinded with masks, adult male water striders (Gerris remigis) accurately ascertain the sex of other adult water striders in the laboratory. Freely moving females that were artificiallyExpand

Spider flexibly chooses aggressive mimicry signals for different prey by trial and error
Portia is a jumping spider that invades other spiders' webs, makes vibratory signals that deceive the resident spider (aggressive mimicry), then attacks and eats the spider. Portia exploits a wideExpand

Observations in nature of detouring behaviour by Portia fimbriata, a web‐invading aggressive mimic jumping spider from Queensland
Portia fimbriata, a web-invading, araneophagic salticid that uses aggressive mimicry to deceive its prey (web-building spiders), takes indirect routes to reach its prey (i.e. it makes detours). DataExpand

Ripple communication in aquatic and semiaquatic insects
Abstract:Among insects, ripple communication has been described in water striders (Gerridae) and giant water bugs (Belostomatidae), although it also seems likely to occur in whirligig beetlesExpand

Anti‐predator defences of Argiope appensa (Araneae, Araneidae), a tropical orb‐weaving spider
Anti-predator defence behaviour of Argiope appensa (Fuesslin) (Araneae, Araneidae) was studied in the laboratory. The most frequent response of adults and large juveniles of A. appensa to disturbanceExpand

Stonefly nymphs use hydrodynamic cues to discriminate between prey
SummaryPlayback experiments conducted in a Rocky Mountain, USA, stream determined whether predatory stonefly nymphs (Kogotus modestus; Plecoptera: PerlodiMae) used hydrodynamic cues to discriminateExpand

Closed‐Form Solution of the Differential Equation (∂2∂x∂y+ax∂∂x+by∂∂y+cxy+∂∂t)P=0 by Normal‐Ordering Exponential Operators
A closed‐form solution to Lambropoulos' partial differential equation (∂2∂x∂y+ax∂∂x+by∂∂y+cxy+∂∂t)P(x, y, t)=0, subject to the initial condition P(x, y, 0) = Φ(x, y), is presented. The applicabilityExpand

Surface Wave Reception in Invertebrates and Vertebrates
At the surface of water, the asymmetry of intermolecular forces, coupled with strong molecular cohesion, produces an elastic, membranelike film. The film can support objects much heavier than water,Expand
