The herbivore list presented below is an ongoing product of collecting
and rearing by Dan Janzen and his Costa Rican assistants in Sector Santa
Rosa of the Area de Conservación Guanacaste, beginning in 1978 (Janzen,
D. H. and Hallwachs, W. 1998 (in prep.). Janzen and Hallwachs Caterpillar
Rearing Database. <http://janzen.sas.upenn.edu/index.html>. Filemaker
Pro 4.0 database accessible through Netscape and other web browsers). This
work has been supplemented by focused collecting by Jon Sullivan (jjsulliv@sas.uenn.edu)
and Alex Perez from 1995 to 1998. All collecting has been based in the dry
forests of Sector Santa Rosa of the Area de Conservacion Guanacaste (ACG),
and most collecting has been restricted to hand-gathering from seedlings
and saplings. Dan Janzen's collections of Tabebuia
ochracea herbivores are part of his massive rearing project focused
on inventorying the macro-lepidopteran larvae of the ACG forests, together
with what they eat, and what eats them.
A selection of photos have been included for some species when available
. To view a page of photos for a species, click on either the larval or
adult reduced photo below. These are not intended to serve as an comprehensive
identification guide. A much larger database of photos, which includes most
of the species below, is being incorporated into the Janzen and Hallwachs
Caterpillar Rearing Database <http://janzen.sas.upenn.edu/index.html>
(this is also databasing records of non-caterpillar insect herbivores of
Tabebuia ochracea). This database
can also be consulted for additional information on natural history, phenology,
parasitoids,.
Many of the below species still require identification, especially the
non-lepidopterans. Future modifications of this page will fill in many of
the gaps.
