To cultivate crops is to risk their destruction by pests. For present-day Maya in highland Guatemala, anxious about fields, these assaults come from “weevils, white grubs, moths, beetles, caterpillars, and aphids…wireworms, mites, crickets, scales, flies, leafhoppers, and ants,” with particular comment on gorgojos, “weevils” (Morales and Perfecto 2000:52). A nuisance, all such insects nonetheless had, by traditional belief, a claim to food, “[h]ay que compartir con los animales” [one has to share with animals]…although farmers still elected to apply lime (loathed by grubs) and botanical pesticides (often from plants harvested locally) (Morales and Perfecto 2000:54, 58). These must have been more effective than a Roman remedy against caterpillars, mentioned by Pliny the Elder (ca. AD 23–79). He recommended “fixing up on a stake the skull of an animal of the horse class, provided it is that of a female…[or] a river crab hung up in the middle of a garden” (Natural History, Book XIX.LVII.159, Pliny 1950:535). Columella, writing a little earlier than Pliny, urged that bear’s blood and beaver skin be smeared on pruning knives, the better to repel the “leaf-roller,” a pest in vineyards (On Trees, XV, Columella 1955:379).
These practices, fanciful or not, reflect a certain desperation. History records many devastations by locusts and other insects, crushing local economies and destabilizing communities (Olvidadase and Dindo 2025:87, Table 1). Such predations could be “catalytic” to social change, if not always “determinative”; that is, they compounded rather than instigated vulnerabilities, yet their effects were still profound (Olvidadase and Dindo 2025:88). Among the Aztecs, droughts were accompanied, in 1446, by a plague of locusts, followed by years of misery (Hassig 1981:172, 173). The Yukatek Maya of the Colonial period were no less distressed by pests. War, “rains of little profit,” hangings of people, defeat: such ill fortune coincided with “a year of locusts” (Roys 1967:154). Hinting at Old Testament fusions (cf. Exodus 13–15), Christianity was said in the Chilam Balam of Chumayel to arrive in another “year of locusts,” along with calamities like “blood-vomit, drought…smallpox…[and] the importunity of the devil” (Roys 1967:164).
Pest management was (and is) an enduring concern in Maya agriculture. A well nourished “postura” or individual planting of maize and bean plants—in Highland Guatemala, the four, sown kernels of such clumps indicate some cosmological import—flourish better with traditional fertilizer, not synthetic ones, which seem more susceptible to infestations (Morales, Perfecto, and Ferguson 2001:146, 153). Beneficial arthopods contribute to pest reduction, so not all bugs are bad (Benrey, Bustos-Seguro, and Grof-Tisza 2024:2, 4). Diminished “pest-pressure” is the goal rather than the complete absence of pests. That there is an acceptable degree of loss fits with an attitude of balanced concessions to other creatures. For insects, especially weevils, as opposed to marauding raccoons and coatimundi, losses are in any case more likely during post-harvest storage (Nations and Nigh 1980:13).
By now, it is well known that the Classic Maya grew agave (maguey) plants and consumed their products, from fibers to saps, including frothy aguamiel and, as its sugars break down into alcohol, the semiotically dense beverage of pulque (Houston, Stuart, and Taube 2006:116–117, 120, 122; Looper and Rehg 2023; Tokovinine 2016:16, figs. 3, 4; see also Barrera Vásquez 1941). Renowned for its preservation and care of excavation, Cerén, El Salvador, shows as many as 70 maguey plants for one household alone (Sheets 2017:108; Sheets and Woodward 2002:186–188, fig. 20.2). In highland Mexico, the use of maguey extends to clothing and cordage, fuel and construction material, particularly in areas where cotton does not grow well and deforestation has taken its toll (Parsons and Parsons 1990:4).
Ritual incantations to maguey in 17th century Nahuatl coax and encourage the plant: “[l]et it be soon! …here is the good place, the fine place that I have swept for you. Here you will be sitting” (Ruiz de Alarcón 1984:122). That people talk to plants, and that they presumably listen, signals a discursive, ritualized care beyond planting, pruning, and harvesting. At Teotihuacan, also in highland Mexico, pulque was a nutritional resource and risk-buffering food as well as a filling, potable liquid (Correa-Ascencio et al. 2014:14223, 14227; only one small sector of the city was sampled, but the results are likely relevant to Teotihuacan in general). Fiber processing is well-documented among the Classic Maya too, for glyphic evidence points to use of special metates (grinding stones) for pounding and grinding maguey fiber (Stuart 2014). At times of privation—the Mexican Revolution is one such period—maguey became, in some areas of highland Mexico, almost the sole means of sustenance (Parsons and Parsons 1990:11). Yet there is always pleasure mixed with pain. Known as chih in Classic Maya sources, pulque is said to be only slightly inebriating, but that effect must have been intensified by episodic use, binge drinking (especially among young men), and rectal ingestion, bypassing the stomach and its less speedy processing of alcohol (Houston 2018:128–130). The lack of restraint in Maya scenes of drunkenness is anything but decorous.
A notable feature of aguamiel and pulque is their need for “formidable management,” i.e., care of plants not yet yielding product, attention to when plants start their final “death-bloom,” extraction of aguamiel, and, as a special urgency, its transport as a fermented drink to consumers (Parsons and Parsons 1990:18). Pulque spoils quickly. For maguey, the telltale sign of maturation, and a portent of its imminent demise, is the astoundingly rapid growth of stalks (with seeds) some 4 to 8 m in height (Figure 1, Parsons and Parsons 1990:29). Exuberant life is soon followed by death. It is perhaps for this reason that the Classic Maya link the agave plant to skulls and skeletons, reflecting its tough exterior but also its impending demise (Houston and Scherer 2020:figs. 1, 2). In one image, K1822, from the Kerr archive of Maya pots, the glyph for maguey merges with the head of one version of the Maya rain deity, ‘O Chahk, savoring of seasonality and cycles of moisture (see also Dine and Houston 2026). Depending on location and species, the plant appears to bloom largely in late spring or through the summer, and this merger of plant and rain god may express some tinge of that timing. (Typically, in the Maya region, that is a period with heavy rainfall.) An added urgency with agave is that, in its final burst, the plant will consume all its sap. Humans have to intervene early, at just the right time. Premature collection will result in too little liquid, unpalatable at best; the same will occur if collection takes place beyond a window of 2 to 3 weeks (Parsons and Parsons 1990:29; see also Escalante et al. 2016:3–5, Table 1, which tabulates many different species of agave yielding aguamiel and pulque). Within months, possibly up to a year, the plant will die from this extraction, as part of its so-called “castration.” There may have been an emotional resonance to this. On one pot, the gesture of the skeletal deity of maguey displays the arm upright and bent in a well-attested gesture of lamentation (Houston and Scherer 2020:fig. 2). Death is nearby, expectant.

Humans are not the only creatures to use maguey and consume its fluid. A dire competitor is the Agave Snout Weevil, Scyphophorus acupunctatus, which grows to some 8 to 19 mm in length (Figure 2). A real threat to modern production of tequila, a distilled residue of maguey sap, they attack boles and, by weakening the plant, contribute to other, rotting diseases (Cuervo-Parra 2019:2; Figueroa-Castro et al. 2013:1455; Waring and Smith 1986). To judge from modern evidence, shifts in climate appear to spur their activity and ability to destroy stands of maguey, perhaps an economic stressor in the past as well (Salazar-Rivera et al. 2026). Weevil larvae munch on the plant, but the adult drills in, leading to one term for “weevil” in Colonial Tzotzil, joch’, “woodborer,” from a word for “drill” (Laughlin 1988, I:211).

A unique image of an Agave Snout Weevil exists on a chocolate vase from the area of Naranjo, Guatemala (Figures 3, 4, 5, Looper and Rehg 2023). It dates to the later 6th century AD, and, the work of a widely productive painter, was formerly in the collection of Landon T. Clay; a fire at his residence led to its complete loss (Dorie Reents-Budet, personal communication 2026). The text above may note the name of the owner, or, possibly, a term for “white pulque,” SAK-chi? . The name and titles of “Aj Num Saaj,” ruler of Naranjo, follows (see Tokovinine, Estrada-Belli, and Fialko 2024:787–791; by a conservative view, the precise reading of the ruler’s name is still conjectural, hence the quotation marks). For the moment, the most sure bet is that this spells a nominal. The ruler who owned or commissioned this and many other vases—more than a dozen exist, some from archaeological settings—favored mythic narratives with cavorting birds, animals, and bugs (Houston and Tokovinine 2016). The pot reveals a scene in which a bipedal jaguar looks across a maguey plant to a seated armadillo and a mosquito. All animals speak or vocalize, a fact plain from the dotted streams coming from their mouths. In between is an umistakable agave plant, resting on a skull with some touches of the rain god’s head. From the plant, sprouting in aureole glory, is the quiote or scape, the stalk that grows with surprising speed. Ordinarily, on actual plants, several flowers appear—they are a rare delicacy, especially if boiled in salted water (Figueredo-Urbina, Álvarez-Ríos, and Zárraga 2021)—but a need for representational economy may have limited it to one illustration here. Painting in other growths would have cluttered what is already a tight visual space. The flowering suggests the agave has not been castrated nor aguamiel extracted; the plant is in its final death-bloom, a tenuous time, even of slow-motion crisis. A particular time of year is implicated, perhaps from late spring to late summer.

The bug at the center, the bole of the plant, is crucial. Patently, it is an Agave Snout Weevil (Figure 6). For ancient America, this representation is among the only such plant pests ever identified in ecosystemic relation to its host. [Note 1] Like the weevil, it is black; it has three protruding elements, again like the bug. Its cramped, flexed body shape compares to other burrowing insects, and it sits at the bole of an agave where the weevil feeds (Houston 2025). When active, the weevil leaves a dark, rotting mass. The insects also make a loud clicking noise while dining. That is duly cued by the single dotted emission coming from its snout. A noisy group in general: even the mosquito emits what may be its high-pitched whine (Figure 3).

The identification is crisp, but the larger setting of gathered feline, armadillo, and agave pest remains opaque. Other pots of this time and place, including one in The Mint Museum in Charlotte, NC (1985.102.5, K1558), highlight similar interactions and revelries of beasts and bugs. The obscurity is also high, of stories, some etiological or explanatory, that lie “off-pot,” a sum of inaccessible, background knowledge that is assumed for viewers. A larger question, of what is conventional, what closely observed, further clouds the pot. The Agave Snout Weevil is both recognizable and stylized, a conundrum in lexical classification generally. It exists between a local subjectivity, perfectly serviceable to ancient Maya, and a Linnean “scientific realism” that might derive from microscopy, cladistics or DNA-based classes (Amundson 1982:241; Rossi and Newman 2025:35). Loose congruence between the two will almost always exist; consummate congruence, never.

Shanti Morell-Hart provided good advice, as did Andrew Scherer. Dorie Reents-Budet was most collegial in permitting use of the photographs featuring the weevil. From Berlin, in the middle of a busy schedule, she also sent other photos of this now-lost pot. I am grateful for that help.

Christian Prager (personal communication, 2026) wonders whether worms and other plant-predators appear on the pages of the Madrid Codex, albeit with terse and mostly uninterpretable texts (see Madrid 25d, 27d, 28c).
