Figure 7 in Computational investigation of cicada aerodynamics in forward flight
Figure 7. (a – f) Time course of vortex development, visualized by the Q-criterion. The left and middle columns are back view and top view, respectively, and the vortex structures are coloured by spanwise vorticity. The right column shows the structures in projection view, coloured by streamwise vorticity. Colour bars in the first row apply to figures in the same column.

FIGURE 3. COX I in DNA barcoding of new world cicada killers (Hymenoptera: Crabronidae)
FIGURE 3. COX I gene tree resulting from NJ analysis of the full data set, including 56 Sphecius sequences. Bootstrap values greater than 70% are provided above the branches. Haplotype symbols match those used in Fig. 1. Abbreviations after each name indicate the state where the individual was collected (and gc indicates Grand Canyon National Park). When multiple individuals from a state were used in the analysis, they are numbered.
FIGURE 2. COX I in DNA barcoding of new world cicada killers (Hymenoptera: Crabronidae)
FIGURE 2. COX I gene tree resulting from NJ analysis of the BBNP data set. Bootstrap values greater than 70% are provided above the branches. Haplotype symbols match those used in Fig. 1. Note that S. speciosus and the majority of S. convallis individuals have the same haplotype. The different symbols here emphasize that these are different species.
FIGURE 1 in DNA barcoding of new world cicada killers (Hymenoptera: Crabronidae)
FIGURE 1. Geographic distribution of mitochondrial haplotypes for individuals of the three Sphecius species sampled from the USA. Approximate localities for all 54 individuals are shown. (Note: S. spectabilis does not occur in the USA; the two individuals sampled were Argentinean).
FIGURE 4. COX 1 in DNA barcoding of new world cicada killers (Hymenoptera: Crabronidae)
FIGURE 4. COX 1 gene tree resulting from maximum likelihood analysis of the pruned data set, with duplicate Sphecius sequences removed. Bootstrap values greater than 70% are provided above the branches. Haplotype symbols match those used in Fig. 1.
Fig. 3 in Dead-twig discrimination for oviposition in a cicada, Cryptotympana facialis (Hemiptera: Cicadidae)
Fig. 3 Kinematic diagrams for oviposition-related behaviors. Sequential relationships between behaviors, which occurred successively within 60 s, are linked with lines for females hung on a wood stick (a, from 25 females), a dead twig (b, from 24 females), or a live twig (c, from 25 females). The number in a box is a cumulative total number of observations of each behavior. The number associated with a line is the number of observations of a flow, and the thickness of a line indicates its proportion relative to the total number of sequences, except that flows constituting less than 10 % are depicted as broken lines. T-shaped lines indicate the end of a sequence that did not lead to oviposition. For the definition of each action, see Table 1
Fig. 2 in Dead-twig discrimination for oviposition in a cicada, Cryptotympana facialis (Hemiptera: Cicadidae)
Fig. 2 Effects of oviposition substrates on induction and success of oviposition. An adult female was caged with one of the three oviposition substrates, and its behavior was observed for 90 min. a The number of ovipositions completed per female. b The number of oviposition trials, that is, initiation of boring, per female. c Completion rates of oviposition trials. Data are shown by Tukey box plots; they indicate the median (bold line), the 25th and 75th percentiles (box edges),
