| Abstract |
Insects represent most of terrestrial animal biodiversity, and multiple reports suggest that their populations are declining globally due to anthropogenic impacts. Yet, a high proportion of insect species remain undescribed and limited data on their population dynamics hamper insect conservation efforts. This is particularly critical in tropical biodiversity hotspots such as Southeast Asia. To identify knowledge and capacity gaps in Southeast Asian insect conservation, we performed a quantitative review of insect occurrence records, studies for the region and global '#conservation' posts from Twitter. We found that occurrence records increased over time, and were dominated by butterflies. Overall, studies were largely focused on pest and vector groups, and insect conservation and ecology studies were lacking in many countries. Despite an increase in local authorships and funding sources over time, the majority of these were still located outside of Southeast Asia. In '#conservation' posts, insects were highly under-represented and insect-related content was biased towards popular groups such as bees and butterflies. We suggest potential solutions to address these gaps, such as integrative taxonomic approaches, and increasing regional collaborations and public engagements. Crucially, we stress the need for political will and funding to overcome the impediments towards insect conservation efforts in Southeast Asia.
