Genus Solenopsis Westwood 
Markin et al. (1972: 1053): Life cycle of Solenopsis invicta 
Buren in an incipient colony: egg 6-8 days, larva 14-15 days, pupa 
20-24 days. 
Genus Tetramorium Mayr 
Tetramorium caespitum (Linnaeus). Donisthorpe (1927: 197): 
“The larvae were fed with disgorged liquid food as long as they 
were young and gathered together in groups, but when they grew 
older and were separated, the workers fed them with solid sub- 
stances.” Many larvae were hung on to the plaster walls of the nest 
by their anchor-tipped hairs.
