These two parataxonomists (“gusaneros” in the vernacular) – Calixto Moraga and Manuel Ríos - at Estación Biológica Pitilla are returning to the caterpillar rearing barn from a rain forest search, with their victims in bags with their food plants and bearing magnificent shelter from the elements.

This is the majority of the members of the ACG Costa Rican resident parataxonomist team (a.k.a “gusaneros”) in 2008 (Estación Biológica Santa Rosa).
No full text<p>Each is labeled with the number of years he or she has worked conducting the ACG caterpillar inventory, and adult moth and butterfly inventory (BioLep). Image credit, Daniel Janzen.</p
These two parataxonomists (Freddy Quesada and Harry Ramirez of Estación Biológica Cacao) are doing routine data entry in the rearing barn on the day of caterpillar collection.
No full text<p>Plastic bags hanging in the background contain pupae waiting to eclose, while caterpillars in their bags with fresh foliage are outside in indirect sunlight. Harry is ensuring that Freddy enters the correct species name for the food plant in the record they are constructing (February 2003). Image credit, Daniel Janzen.</p
This map outlines Area de Conservacion Guanacaste (ACG) Life Zones as overlain with caterpillar inventory rearing barns (red circles) and general transit access roads and trails (red lines).

This is a box (same size as the white box in <b>Figure 8</b>) of reared, databased, spread and oven-dried ACG small moths and butterflies, in the form that they were delivered by a parataxonomist (Johan Vargas) to the Santa Rosa clearing center.
No full text<p>Each specimen has its unique voucher code on its pin, and each will lose one leg to the barcoding process by Tanya Dapkey as it passes through the central clearing center at the University of Pennsylvania on its way to permanent residence in the Smithsonian Institution, INBio, Canadian National Collection, or other museum.

Report on Meteorological Research March 1, 1935 (m-1)
No full textThe object of the report was to elucidate in detail the various features of the research program in meteorology being carried on at the Daniel Guggenheim Airship Institute in Akron, Ohio. Mr. L. J. Fangman, of the U.S. Weather Bureau, was collaborating with the author in carrying out work such as a study of autographic records of the various meteorological elements during frontal passages with a view to the possible prediction of the intensity of the accompanying disturbance as it may affect the operation of aircraft and a study of atmospheric gustiness with a view to finding the dependence between frequency end amplitude of velocity fluctuations and the vertical temperature and velocity gradients

These two BioLep parataxonomists (Hazel Cambronero and Sergio Ríos) are collecting at a car-battery-powered light (Sector Santa Rosa) in order to construct the adult Lepidoptera ACG barcode library.
No full text<p>Each moth is collected individually into a small used-only-once plastic bag to avoid contamination with the scales from other moths, and then frozen, later to be sorted while still in the bag, before spreading and drying for subsequent de-legging for barcoding. More than 4,000 species of moths have been collected from this particular light in the three decades of moth inventory of ACG. (June 2006). Image credit, Daniel Janzen.</p
