Common Green Colonel

<em>Oplodontha viridula</em>, commonly known as the common green colonel, is a soldier fly belonging to the genus Oplodontha within the family Stratiomyidae. This species inhabits virtually all terrestrial and freshwater habitats, with a documented range that includes Belgium, Denmark, Norway, and Sweden in northwestern Europe. Notably, <em>Oplodontha viridula</em> is assessed as Vulnerable on the IUCN Red List, indicating that it faces a significant risk of extinction if the circumstances threatening its survival continue. Conservation concern for this species likely relates to habitat degradation and the decline of wetland and marginal habitats within its European range. The species typically frequents aquatic and semi-aquatic environments where larvae develop in moist organic substrates. Biological traits of this species remain poorly documented in the scientific literature.
