The classification of stick and leaf insects (Order Phasmatodea) is flawed at various taxonomic ranks due to a lack of robust phylogenetic relationships and convergent morphological characteristics. In this study, we sequenced nine new mitogenomes that ranged from 15,011 bp to 17,761 bp in length. In the mitogenome of Carausis sp., we found a translocation of trnR and trnA, which can be explained by the tandem duplication/random loss (TDRL) model. In the Stheneboea repudiosa Brunner von Wattenwyl, 1907, a novel mitochondrial structure of 12S rRNA-CR1-trnI-CR2-trnQ-trnM was found for the first time in Phasmatodea. Due to the low homology of CR1 and CR2, we hypothesized that trnI was inverted through recombination and then translocated into the middle of the control region. Control region repeats were frequently detected in the newly sequenced mitogenomes. To explore phylogenetic relationships in Phasmatodea, mtPCGs from 56 Phasmatodean species (composed of 9 stick insects from this study, 31 GenBank data, and 16 data derived from transcriptome splicing) were used for Bayesian inference (BI), and maximum likelihood (ML) analyses. Both analyses supported the monophyly of Lonchodinae and Necrosciinae, but Lonchodidae was polyphyletic. Phasmatidae was monophyletic, and Clitumninae was paraphyletic. Phyllidae was located at the base of Neophasmatodea and formed a sister group with the remaining Neophasmatodea. Bacillidae and Pseudophasmatidae were recovered as a sister group. Heteroptergidae was monophyletic, and the Heteropteryginae sister to the clade (Obriminae + Dataminae) was supported by BI analysis and ML analysis.

The Phasmatodea Order is represented by terrestrial insects, phytophagous and wide distribution. About 200 species have been described in Brazil as Cladomorphus phyllinus. The aim of this study was to describe the biology as well as measure population parameters. The specimens were kept in cages with temperature and natural photoperiod. We used 22 animals that were fed with leaves of guava, Psidium guajava Linnaeus. For the construction of the dynamic life table, the following parameters were used: specific survival by age group; survivorship or survival compared to live-born animals; specific fertility by age group; specific mortality by age group and life expectancy. Initially, the cohort of animals was monitored weekly, for a total period of 55 weeks. However, to facilitate data tabulation, they were grouped into age groups. The cohort was then divided into 11 periods of 35 days each; thus totaling 385 days. The survival curve, constructed with the survivorship data, indicate to a curve of type II, where the mortality rate is relatively constant throughout life. The animals began to lay eggs at the 23rd week. The period with the highest fecundity was t5 with 93 eggs per female. With the life table, the population projection was performed in future time intervals. In the time t = 291, the λ value stabilizes at 2.0747 and the population reaches stable age distribution. The data indicate high biotic potential for the species, in contrast to the density of data in the field, when the group is usually found in low densities, probably indicating low effectiveness of camouflage combined with the fragility of the animals against environmental adversities.
