Insects of La Saladita
Butterflies, Beetles & Dragonflies.

Lagoon dragonflies, coastal butterflies, and remarkable beetle diversity in the mangrove and tropical dry forest behind the beach. A field guide to the insect life of the La Saladita corridor.

La Saladita · 17.5897°N, 101.4317°W · Guerrero, Mexico
Data note: iNaturalist and GBIF records for this region are moderate-to-sparse relative to better-surveyed areas. The 5,350 combined records and 1,514+ species documented here reflect citizen-science effort and research survey coverage, not the true richness of what lives here. Many species present in these tropical habitats are likely unrecorded. Counts are honest proxies, not ceilings.

Freshwater, saltwater, and dry scrub within a few hundred metres creates exceptional insect habitat — the estuary alone draws dragonflies, damselflies, and aquatic beetles that don't appear elsewhere on the coast.

Listen for these — the soundscape

The dry forest behind Saladita has its own daily acoustic schedule. Cicadas dominate the heat of the day with droning calls audible from hundreds of meters. Crickets take over after dusk. These are the most likely callers — recordings from iNaturalist research-grade observations of the same species at other Mexican Pacific sites.

Giant Cicada
Quesada gigas
Iconic dry-season call · heard at midday
CC BY-NC-ND · via iNaturalist

The largest cicada in the Americas (~6 cm). Loud rasping song carries across the forest canopy; one of the dominant sounds of the Mexican Pacific dry season.

Tropical House Cricket
Gryllodes sigillatus
Night chirp · pantropical
CC BY-NC · via iNaturalist

Sharp, evenly spaced chirps after dusk. The cricket you hear from the casita at night, every night, all rainy season.

Variable Field Cricket
Gryllus lineaticeps
Trilling chorus · grassy edges
CC BY-NC · via iNaturalist

Lower, more continuous trill than the house cricket. Two or three calling together produce a wash of sound; dozens make a chorus.

Cri-cri Tree Cricket
Oecanthus rohiniae
Soft purring · shrubs and trees
CC BY-NC · via iNaturalist

Tree crickets are the soft pulsing sound behind the louder field crickets — a continuous purr from the shrub layer. Recently described from Mexico (2019).

Bruner Longwing Katydid
Capnobotes bruneri
Long buzz · dry scrub at night
CC BY-NC · via iNaturalist

Sustained buzzing call distinct from the crickets — coarser, longer-pulsed. Range-confirmed for the Mexican Pacific dry forest; the most likely large katydid you'll hear at Saladita.

Photos and audio via iNaturalist (CC-licensed). Insect diversity here is enormous — these are highlights. Butterflies are the signature group, with the dry forest behind the village supporting dozens of species in the wet-season flush. Fireflies (Photinus) peak from mid-June through early August in synchrony with the first rains. Mosquitoes (Aedes aegypti) are the most medically important: dengue and Zika both circulate regionally. Use repellent at dawn and dusk during rainy season.

Black Setwing
Erythrodiplax funerea

Freshwater, saltwater, and dry scrub within a few hundred metres creates exceptional insect habitat. Butterflies best-documented: 100+ species within 25 km. Notable: barred yellow (*Eurema daira*), banded peacock (*Anartia fatima*), crimson-patched longwing (*Heliconius erato*), migratory monarch in late autumn. Lagoon dragonflies: black-winged dragonlet (*Erythrodiplax funerea*), carmine skimmer (*Orthemis discolor*), great pondhawk (*Erythemis vesiculosa*). Beetles: most species-rich order on Earth, most undersampled here — current data skews toward photogenic lady beetles. Secondary Jul–Aug peak when rainfall triggers flowering and fungi.

Notable groups

Three orders, three habitats

🦋 Lepidoptera

Butterflies & Moths

The best-documented insect group here. Open scrub, beach vegetation, and flowering trees provide continuous nectar through much of the year. Sulphurs, whites, nymphalids, swallowtails, and blues are all well represented. Migratory Monarchs (Danaus plexippus) and sulphurs pass through Sep–Nov on their southbound movement along the Pacific coast.

Top recorded species (iNat + GBIF, 2000–2025)
  • Eurema daira — Barred Yellow n=66
  • Hemiargus ceraunus — Ceraunus Blue n=56
  • Ascia monuste — Great Southern White n=48
  • Anartia fatima — Banded Peacock n=46
  • Marpesia petreus — Ruddy Daggerwing n=45
  • Euptoieta hegesia — Mexican Fritillary n=44
  • Battus polydamas — Polydamas Swallowtail n=41
  • Heliconius erato — Red Passion Flower Butterfly n=41
🪲 Odonata

Dragonflies & Damselflies

The estuary lagoon behind the beach is the key habitat. Dragonlets, skimmers, pondhawks, and dashers patrol the water margins year-round. Damselflies — firetails and damsels — are present but undersampled due to size. The strongest records come from Jan–Feb and the rainy season (Jul–Sep) when lagoon water levels are highest.

Top recorded species
  • Erythrodiplax funerea — Black-winged Dragonlet n=37
  • Orthemis discolor — Carmine Skimmer n=18
  • Erythemis vesiculosa — Great Pondhawk n=17
  • Telebasis salva — Desert Firetail n=15
  • Dythemis sterilis — Brown Setwing n=9
  • Micrathyria hagenii — Thornbush Dasher n=8
  • Perithemis intensa — Mexican Amberwing n=6
🪲 Coleoptera

Beetles

Almost certainly the most species-rich insect order in the mangrove and dry forest — but the most undersampled in the data. Current records are biased toward conspicuous lady beetles and leaf beetles. Longhorns, buprestids, weevils, and ground beetles likely constitute the majority of local beetle diversity but require deliberate searching and specialist identification to record.

Top recorded species — data likely underrepresents true diversity
  • Epilachna tredecimnotata — Southern Squash Lady Beetle n=21
  • Zopherus nodulosus — Iron-clad Beetle n=15
  • Deloyala lecontei — Tortoise Beetle n=15
  • Cycloneda sanguinea — Spotless Lady Beetle n=12
  • Charidotella sexpunctata — Golden Tortoise Beetle n=12
  • Chilocorus cacti — Cactus Lady Beetle n=11
  • Acmaeodera trizonalis — Jewel Beetle n=11
Soundscape

The insect chorus

Cicadas dominate the dry-season soundscape (December–April). Multiple Diceroprocta and Tibicen species produce the high-volume chorus audible from the beach. Crickets and katydids take over at night near the lagoon margins year-round.

🦗 Hemiptera — Cicadidae

Cicadas

The loudest sound in the dry-season landscape. Cicada choruses begin at dawn and peak mid-morning; the amplitude is remarkable at close range. Multiple species documented in the Guerrero dry forest. iNaturalist sound observations for this group, when available, can be found via the link below — run the build script to embed them directly.

🦗 Orthoptera — Gryllidae

Crickets & Katydids

Nocturnal chirping near the lagoon and beach scrub, audible every night year-round. Several Gryllus and Neoconocephalus species documented in this coastal corridor. Most active Aug–Nov during and after the rainy season. The sound is a constant backdrop at any accommodation near the estuary.

Most frequently recorded

Top species (effort-normalized)

  • Eurema dairaUncommon · 1.23%
  • Hemiargus ceraunusUncommon · 1.05%
  • Marpesia petreusUncommon · peak Aug–Sep
  • Erythrodiplax funereaUncommon · peak Aug–Sep
  • Orthemis discolorUncommon · peak wet season

With 5,350 total insect records and 1,514 species, no individual species exceeds the 3% "Common" threshold. All top-30 are "Uncommon" by frequency. November bias corrected: wet-season species (Jul–Oct) were systematically undercounted in raw data — effort normalization restores their true peak timing.

Real peak season

Jul–Oct, not November

Raw records spike in November (1,439 obs vs 68 in May) — a 21× observer bias driven by peak tourist season. After effort normalization, the biological peak is July–October (wet season). Species like Marpesia petreus (Ruddy Daggerwing) and Erythrodiplax funerea were miscategorized as November species in raw counts. Their real peak is August–September.

Top 30 insect species by combined iNaturalist + GBIF records within 25 km of La Saladita, 2000–2025. Lepidoptera dominate — a reflection of observer interest, not ecological dominance.
