Strymon astiocha
species of insect
Strymon astiocha is a butterfly of the family Lycaenidae. It is found in Brazil, including the states of Rio de Janeiro and Rondônia.
Description
The species exhibits sexual dimorphism in size, with males being about the size of Alexis. The wingspan is similar to other Strymon species in the region. The forewings are white with brown coloration on the body, breast, and a very short tail-like projection. The antennae are black with white bands.
The hindwings have distinctive markings including a black line in front of the fringes, from which individual dark stripes extend into the wing margins. Above this line is a whitish line on the posterior part of the hindwings, with 2 to 3 large black spots located right and left from the hindmost branch of the median vein.
The underside of the forewings shows brownish-gray coloration from the base for about two-thirds of the wing length. The wing pattern includes a brown shadow, a series of small dark-brown crescent-shaped spots, a white zigzag line with gray filling, a series of gray spots, a fine dark line, and white and gray checkered fringes.
This brief starts where responsible research should: with the source description of “Strymon astiocha” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 2, 2025. The linked authority identifier is Q25359160. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
