animal quarantine facility and with little vegetation other than 
mangroves, pioneering stage herbs, and introduced ornamental 
trees, such as Casuarina. Such environments select for unusually 
hardy ichneumonids and species of this type should particularly 
concern the biological control specialist, who is looking for para- 
sites that will thrive in climatically stressed agricultural systems. 
The Fleming Key Survey, run between May 1979 and May 1980, 
with a gap in September and October, amassed 631 ichneumonid 
specimens belonging to 37 species. Only 9 of these species accounted 
for about 89% (561 specimens) of all Ichneumonid ae trapped. Dia- 
degma sp. (22 specimens) was the least abundant of the “common” 
group, followed by Compsocryptus fasciipennis (23), Labena gralla- 
tor (36), Mallochia agenioides (41), Anomalon sp. (43), Temelucha 
sp. (68), Paraditremops albipectus (103), Calliephialtes ferrugineus 
(107), and Eiphosoma dentator (118, Porter 1983). 
Table 1 summarizes monthly phaenology for Compsocryptus fas- 
ciipennis and the eight other common ichneumonid species of the 
depauperate Fleming Key Fauna, as sampled by Malaise traps. 
Compsocryptus fasciipennis is active from fall to late spring with 
maxima in March and October (as shown by Malaise and hand 
collected specimens). This seasonal phaenology coincides approxi- 
mately with that of the Argentine C. melanostigma and agrees even 
more closely with the pattern shown by C. texensis in the Lower Rio 
Grande Valley (present from January to May and again in 
December with greatest abundance in December, as documented by 
Porter, 1977:82). 
Compsocryptus fasciipennis follows a cool-season phaenologic 
cycle not unlike that of many other ichneumonids which inhabit 
subtropical communities from Florida and Texas to Argentina. 
Among the abundant Ichneumonidae at Fleming Key, 4 species 
have autumn to early spring maxima and roughly parallel C. fascii- 
pennis (Calliephialtes ferrugineus, Paraditremops albipectus, Teme- 
lucha sp., and Diadegma sp.), 2 peak in May (Labena grallator, 
Anomalon sp.), and the other 2 become most abundant during July 
and August (Eiphosoma dentator, Mallochia agenioides). Nonethe- 
less January to March seem the best overall months for ichneumon- 
ids at this locality. All 9 species occur during this trimester and 230
