“…S obs: observed richness.Five species, Eumorpha phorbas (Cramer, 1775), Isognathus excelsior(Boisduval, [1875]), Oryba kadeni (Schaufuss, 1870), Pachylia darceta and Manduca leucospila(Rothschild & Jordan, 1903) are recorded for the first time in the northeastern region. These species were recorded previously mainly in the Amazon biome(Motta, Ferreira, & Aguiar, 1991;Motta, Aguilera-Peralta, & Andreazze, 1998;Motta & Andreazze, 2001;Motta & Xavier-Filho, 2005;Lourido et al, 2018;Conceição & Teston, 2020) Martin et al (2011). also recorded Oryba kadeni, Eumorpha phorbas and Manduca leucospila in the Atlantic Forest of Serra dos Órgãos, Rio de Janeiro State;Camargo et al (2018) recorded Pachylia darceta in the Cerrado in the states of Maranhão and Minas Gerais, and according toHaxaire and Mielke (2019) this species also occur in the state of Santa Catarina.In the Catálogo dos Lepidoptera Cearenses,Silva (1967) cited the only reference of the Manduca lucetius (Cramer, 1780) in the Northeast.…”

“…Sphingidae (hawkmoths) is worldwide acknowledged for its important role in pollination, interactions with plants and as bioindicators (Camargo, Camargo, Corrêa, Vilela, & Amorim, 2018). They are found in all continents except for Antarctica and Greenland (D'Abrera, 1986;Kitching & Cadiou, 2000;Hilty & Merenlender, 2000;Darrault & Schlindwein, 2002;Motta & Xavier-Filho, 2005;Duarte, Marconato, Specht, & Casagrande, 2012;Amorim, Wyatt, & Sazima, 2014;Lourido, Motta, Graça, & Rafael, 2018;Conceição & Teston, 2020).…”

The diversity of hawkmoths (Lepidoptera: Sphingidae) is poorly known in the biomes of the Bahia state. However, studies were carried out in other states of the northeastern region with species inventories in the Atlantic Forest, Caatinga and Cerrado. In order to bro aden the knowledge on of the richness and diversity of hawkmoths in the Atlantic Forest of the state of Bahia, six monthly sampling sessions were carried out in the State Ecological Station of Wenceslau Guimarães. Hawkmoths were captured using a 250-watt mercury-vapor light trap set against a white cloth panel, for two nights a month, between 6:00 p.m. and 6:00 a.m. A total of 266 specimens were collected, distributed across 17 genera and 41 species. The most abundant and dominant species were Isognathus swainsoni C. Felder, 1862, with a relative abundance of 12.41%, and Xylophanes amadis (Cramer, 1782) and Xylophanes anubus (Cramer, 1777), both with 7.9%. Our study represents the second inventory of hawkmoths for the state, totaling 59 species known for the Atlantic Forest of Bahia. Isognathus excelsior (Boisduval, [1875]) and Manduca lucetius (Cramer, 1780) represented new records for the biome. The accumulated number of species indicates the need for further sampling in order to safely reach the curve asymptote.

“…This installation was placed at each site with a white sheet facing only the particular sampling site. The techniques used to sample hawkmoths almost resemble those described in Kingstone & Nummelin [35], Ferro & Romanowski [36], and Lourido et al [37]. All three habitat types were surveyed between 18:00 and 24:00 hours, 5 days each.…”

Pollinators are now facing a drastic biodiversity fall in various parts of our world. In Africa data to measure and monitor their biodiversity trend is still inadequate and concentrated more on some insect pollinator groups, especially bees and butterflies. In this study, hawkmoth diversity and abundance in East Usambara Mountains were assessed. Data collection was conducted from three different habitat types that included thick vegetation assemblage with canopy cover, edges of the forest, and farmlands between 2017 and 2019. Hawkmoths were captured using a UVlight trap 250W mercury bulb in 12 sampling sites. A total of 35 hawkmoth species and 991 individuals belonging to the family Sphingidae were identified. The highest hawkmoth abundance was recorded from forest edges (p < 0.05). Canopy cover and farmlands showed lower hawkmoth abundance. Accordingly, higher Shannon Weiner diversity indices were recorded from canopy cover and forest edges (p < 0.05). Farmlands had the lowest Shannon Weiner diversity index. Differences in diversity and abundance of hawkmoths among three habitat types suggest that accelerating anthropogenic factors has led to the destruction of natural habitats. Meanwhile, natural habitat destruction has often been found to exert adverse effects on biodiversity. Moreover, the decline in biodiversity of pollinator insects like hawkmoths hinders the vital pollination service to both crops and wild flora. East Usambara Mountains are still an important refuge for many species that become restricted to different environments due to climate change and anthropogenic pressure, hence calling for regular pollinator conservation and monitoring. This study will provide the baseline data on hawkmoth species richness, abundances and diversity for potential conservation and monitoring programs.

Tropical forests are among the most biodiverse biomes on the planet. Nevertheless, quantifying the abundance and species richness within megadiverse groups is a significant challenge. We designed a study to address this challenge by documenting the variability of the insect fauna across a vertical canopy gradient in a Central Amazonian tropical forest. Insects were sampled over two weeks using 6-m Gressitt-style Malaise traps set at five heights (0 m–32 m–8 m intervals) on a metal tower in a tropical forest north of Manaus, Brazil. The traps contained 37,778 specimens of 18 orders of insects. Using simulation approaches and nonparametric analyses, we interpreted the abundance and richness of insects along this gradient. Diptera, Hymenoptera, and Coleoptera had their greatest abundance at the ground level, whereas Lepidoptera and Hemiptera were more abundant in the upper levels of the canopy. We identified species of 38 of the 56 families of Diptera, finding that 527 out of 856 species (61.6%) were not sampled at the ground level. Mycetophilidae, Tipulidae, and Phoridae were significantly more diverse and/or abundant at the ground level, while Tachinidae, Dolichopodidae, and Lauxaniidae were more diverse or abundant at upper levels. Our study suggests the need for a careful discussion of strategies of tropical forest conservation based on a much more complete understanding of the three-dimensional distribution of its insect diversity.
