SUPPLEMENTARY STUDIES ON ANT LARVAE: 
FORMICINAE (HYMENOPTERA: FORMICIDAE) 1 
By George C. Wheeler 2 and Jeanette Wheeler 2 
Introduction 
This article describes formicine larvae received since the prepara- 
tion of our most recent supplement (1980). The larva of Proformica 
has not been previously described. Also included are references to 
formicine larvae in the literature and a discussion of the status of 
Colobopsis. 
The terms describing body profile and mandible shape are 
explained in our 1976 monograph. Our own contributions are cited 
by year and page only. 
Tribe 4. Formicini 
Genus ACANTHOMYOPS Mayr 
The larvae are very active and can quickly change their posture 
from circular to linear or reverse. 
Genus FORMICA Linnaeus 
Alpert and Ritcher 1975:289. Adults of the scarabaeid beetle 
Cremastochilus armatus feed on larvae of Formica fusca and 
Formica obscuripes. 
Genus LASIUS Mayr 
Lasius sitkaensis Pergande 
Akre and Hill 1973. The pselaphid beetle Adranes taylori Wick- 
ham possesses trichomes (tufts of golden hairs) on the abdomen, 
tips of elytra and venter. These trichomes are highly attractive to 
half-grown or smaller ant larvae, less so to larger larvae and 
workers. The beetles are fed by the larvae through trophallaxis and 
obtain other nutrients by feeding on dead larvae and workers. 
Beetles are often seen walking about with larvae actively holding on 
to the trichomes with their mouthparts; Fig. 4 (p. 531) shows a larva 
so attached.
