Remarkable fly (Diptera) diversity in a patch of Costa Rican cloud forest: Why inventory is a vital science

Art Borkent, +58 more
- 27 Mar 2018 - 
TL;DR: The number of species of Diptera in tropical regions has been severely underestimated and the actual number may surpass the number ofspecies of Coleoptera.

Comprehensive inventory of true flies (Diptera) at a tropical site

Brian V. Brown, +61 more
TL;DR: The intensive inventory of a four-hectare tropical cloud forest in Costa Rica for one year yielded 4332 species of Diptera, providing the first verifiable basis for diversity of a major group of insects at a single site in the tropics.
Journal ArticleDOI

Reduced abundance and earlier collection of bumble bee workers under intensive cultivation of a mass-flowering prairie crop.

TL;DR: The findings suggest that mass‐flowering crops such as canola are attractive to bumble bee queens and therefore may lead to higher rates of colony establishment, but also that colonies established near this crop may be less successful.
Journal ArticleDOI

TL;DR: The New World species of Coproica Rondani, 1861 (Diptera: Sphaeroceridae) are reviewed on the basis of over 17,000 examined specimens and eight new species are described.
