| Abstract |
Insects have evolved morphological and physiological adaptations in response to selection pressures inherent to their ecology. Consequently, visual performances and acuity often significantly vary between different insect species. Whilst psychophysics has allowed for the accurate determination of visual acuity for some Lepidoptera and Hymenoptera, very little is known about other insect taxa that cannot be trained to positively respond to a given stimulus. In this study, we demonstrate that prior knowledge of insect colour preferences can be used to facilitate acuity testing. We focus on four psyllid species (Hemiptera: Psylloidea: Aphalaridae), namely Ctenarytaina eucalypti, C. bipartita, Anoeconeossa bundoorensis and Glycaspis brimblecombei, that differ in their colour preferences and utilization of different host-plant modules (e.g. apical buds, stems, leaf lamellae) and test their visual acuity in a modified Y-maze adapted to suit psyllid searching behaviour. Our study reveals that psyllids have visual acuity ranging from 6.3° to 8.7°. Morphological measurements for different species revealed a close match between inter-ommatidial angles and behaviourally determined visual angles (between 5.5°and 6.6°) suggesting detection of colour stimuli at the single ommatidium level. Whilst our data support isometric scaling of psyllids eyes for C. eucalypti, C. bipartita and G. brimblecombei, a morphological trade-off between light sensitivity and spatial resolution was found in A. bundoorensis. Overall, species whose microhabitat preferences require more movement between modules appear to possess superior visual acuities. The psyllid searching behaviours that we describe with the help of tracking software depict species-specific strategies presumably evolved to optimize searching for food and oviposition sites. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 June 2016.
All research outputs
#15,738,224
of 25,371,288 outputs
Outputs from Journal of Experimental Biology
#6,462
of 9,327 outputs
Outputs of similar age
#146,915
of 279,254 outputs
Outputs of similar age from Journal of Experimental Biology
#82
of 131 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,327 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 14.9. This one is in the 28th percentile – i.e., 28% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 279,254 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 131 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
