Figure 6. Population densities of Lyssomanes viridis (Walckenaer) in magnolia 
stand at Tall Timbers fall 1977 to spring 1978. Data points are means between 
surveys made both inside and outside the stand, during the last half of each month. 
encyrtid wasp and 1 aphid (genus Macrosiphon identified by H. A. 
Denmark). Adult males were collected with an unknown dipteran 
and a salticid spider of the genus Hentzia. Adult females were 
collected with a dolichopodid fly, an unknown dipteran and a 
psocid. 
The population density (Figure 6) dropped during the winter, but 
rose in the spring nearly to that of the previous fall, probably 
reflecting inactivity during the winter, rather than a significant 
mortality. The population drop during May is probably a result of 
the death of adults. Adults were only found during the spring and 
early summer. 
Some adult spiders were found in the nest ol a mud dauber of the 
genus Trypoxylon by G. B. Edwards at Newnan’s Lake, Alachua 
County, Florida. A large Trypoxylon was observed during June at 
Tall Timbers and a fresh nest was found on the underside of a 
magnolia leaf. The nest in this case was filled with Araneidae. One 
adult female L. viridis was collected and found to have a large 
mirmithid nematode in its abdomen. No egg parasites were seen. 
Complete life histories have been published for several salticids.
