Forbestra is the only mechanitine genus lacking a thorough life history description and little is known of its biology. Accordingly I describe the immature stages including first instar chaetotaxy, and provide observations on the biology of Forbestra olivencia from Garza Cocha in eastern Ecuador. Morphological characters from the early stages of Forbestra olivencia are identified that are unique to Forbestra and support the close relationship of Forbestra and Mechanitis. Forbestra olivencia was a moderately common butterfly at Garza Cocha during the sample period, far outnumbering other sympatric Forbestra. Ecological observations demonstrate similarities between F. olivencia and Mechanitis, but suggest F. olivencia is more restricted to shaded microhabitats
