Dinoponera measurements
<p>Measurements of females and males made during the taxonomic revision of <em>Dinoponera </em>Roger (Hymenoptera: Formicidae: Ponerinae) species (Dias & Lattke, 2021). All measurements are expressed in millimeters.</p>
Dinoponera quadriceps feeding on a Leptodactylus sp.
<p>A giant queenless ant observed in hard work in order to remove a piece of tissue from the body of a dead frog, a Leptodactylus sp.</p>
Figure 1 in Social facilitation and food partitioning in the queenless ant Dinoponera quadriceps (Hymenoptera: Formicidae)
Figure 1. Pooled results of the association between workers partitioning food (dotted line) and feeding larvae (solid line) during 21 days of experiment. To test the effects of brood on the foraging process, one or two additional fifth instar larvae were added every 2 days in the experimental colonies.

Figure 2. Mean (± standard deviation) of the total number of ants sharing prey (lower-ranked workers) and feeding larvae in brood chamber (higher-ranked workers).
FIG. 6 in Foraging ecology of the giant Amazonian ant Dinoponera gigantea (Hymenoptera, Formicidae, Ponerinae): activity schedule, diet and spatial foraging patterns
FIG. 6. Ritualized territorial contest between Dinoponera gigantea foragers from diVerent colonies at the border of their foraging areas. (A) Ants lock their mandibles together, vigorously antennate each other's head, and constantly kick one another with the Žrst pair of legs. (B) As the contest escalates the dominant ant (right) directs the tip of the gaster against the opponent's body. The subordinate ant eventually walks away as she breaks free.
FIG. 2 in Foraging ecology of the giant Amazonian ant Dinoponera gigantea (Hymenoptera, Formicidae, Ponerinae): activity schedule, diet and spatial foraging patterns
FIG. 2. Frequency distribution of trip duration relative to diVerent activities performed by workers of Dinoponera gigantea in a Brazilian rainforest site. Although foraging ants may be away from the nest for up to 3 h, successful foragers usually return after 30–60 min of searching. Data are based on continuous 12-h observations at colony Nos 9 and 10, from 6.00 a.m. to 6.00 p.m. Two successful foragers from each colony are not included in the graphs because the duration of their foraging trips could not be recorded.

Figure 4 from: Scholes D, Suarez A, Smith A, Johnston S, Paige K (2014) Organ-specific patterns of endopolyploidy in the giant ant Dinoponera australis. Journal of Hymenoptera Research 37: 113-126. https://doi.org/10.3897/jhr.37.6824
Figure 4 - Endopolyploidy of organs by functional system. Cycle value of organs within each functional system (abbreviations "Digest.": digestive; "Reprod.": reproductive). Shown are means ± standard error across 5 replicates of each organ within each system. Systems are presented in descending order of mean cycle value. Bars labeled with letters denote statistical groups determined by Tukey's Studentized range test (significance tested at αfamily = 0.05). Numbers above each bar indicate the number of organs that comprise each respective system.

Figure 2 - Differences in endopolyploidy among body segments. Percentage of endopolyploid (4C, 8C, 16C, 32C, and 64C) nuclei for each body segment. Shown are means ± standard error across 5 individuals. Letters indicate significant (α = 0.05) differences among body segments. Significance was determined by analysis of arc-sine square-root transformed proportions.
