The butterflies often have the appearance of small satyrids or Thecla species; as for instance Euselasia eutychus resembles (particularly beneath) exactly Euptychia helle flying in the same locality, or Thecla themathea; or Euselasia clithra resembles Euptychia chloris and so on.

On the upper surface there is often a very bright reflection of a shining power otherwise not found in any lepidopteran and of a truly wonderful iridescence.

The pupae are covered with fine, fluffy hairs like the larvae, green, held by a belt.

The imagines are partly extraordinarily rare and belong to the few Riodinidae that fly to a considerable height.

They also clap their wings together when at rest like other day butterflies, unlike most of the other Riodinidae which spread them out like the Geometridae.
