locust
Enable an AI agent to recognise a locust, assess its life stage and phase-related behaviour, and decide what observation, containment or management action is justified.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a locust, assess its life stage and phase-related behaviour, and decide what observation, containment or management action is justified.
It can be Observe, photograph and identify it using stage-appropriate diagnostic evidence.; Measure development, physical condition and local crowding with recorded methods.; Record feeding and movement, and link observations to a band or swarm when supported.; Capture, sample or temporarily contain it where authorised and methodologically justified.; Report a suspected locust occurrence with location, time and identification confidence.; Assess whether monitoring, specialist identification or a separate management process is warranted..
Distinguishing features
Require evidence of a locust-forming grasshopper taxon; abundance or crop feeding alone does not distinguish a locust from another grasshopper.
Check grasshopper morphology, including enlarged jumping hind legs and relatively short antennae, against likely cricket or katydid confusion, allowing for damage and life stage.
Distinguish a wingless hopper from an adult using developmental characters appropriate to the identified species; winglessness alone is insufficient.
Assess phase-related behaviour and morphology separately from identity: an isolated or solitary-phase individual can still belong to a locust-forming species.
Distinguish evidence about one animal from evidence about a hopper band or swarm; a collective sighting does not establish every member's individual condition.
Scope
+ Identification as a grasshopper of a locust-forming species, with evidence and uncertainty
+ Egg, hopper and adult development, including reproductive condition
+ Observed crowding response, aggregation and phase-related traits
+ Individual health, feeding, movement and immediate habitat use
+ Membership in observed aggregations and constraints on handling or intervention
- Population dynamics and organisation of an entire hopper band or swarm
- Regional outbreak forecasting and migration models
- Crop condition, yield loss and farm economics
- Pesticide products, application equipment and treatment programmes
- Whole-habitat condition and ecosystem management
- Processed locust food, feed or commodity batches
Characteristics
- Taxonomic identification
- Candidate taxon, identification confidence and supporting diagnostic evidence Determines whether locust identity is supported and which developmental and phase criteria apply.
- Life stage
- Egg | hopper with instar if supported | adult | unresolved Constrains mobility, identification methods and feasible observation or intervention.
- Body length
- mm, with anatomical endpoints and measurement method Supports identification and developmental assessment without treating size alone as diagnostic.
- Phase assessment
- Solitarious | transitional | gregarious | unresolved, using taxon-specific evidence Supports interpretation of aggregation and movement while preserving uncertainty.
- Observed behaviour
- Resting | feeding | jumping | walking | flying | mating | ovipositing | other observed behaviour Separates direct observations from inferred capabilities or intentions.
- Local crowding
- Individuals per m² or nearest-neighbour distance in cm, with observation footprint and time Provides context for phase assessment and aggregation without equating density with phase.
- Wing and locomotor condition
- Stage-appropriate wing development, visible damage and observed locomotor ability Constrains movement and handling decisions.
- Reproductive condition
- Sex and maturity if supported; mating or egg-laying evidence; unresolved Helps assess breeding relevance without inferring reproductive readiness from adult appearance alone.
- Feeding relationship
- Observed food organism or material, plant part and evidence of consumption Distinguishes actual feeding from simple presence on vegetation.
- Aggregation membership
- Linked hopper band, swarm or other aggregation, with time and membership evidence Connects individual observations to collective assessment without duplicating the collective model.

Locust identity Evidence that the observed organism belongs to a locust-forming grasshopper taxon.
Locust identity cannot be established solely from crowding, colour or agricultural damage.
Taxonomic evidence
Diagnostic observations and the identification methods that interpret them.
Supported locust identification
Record the proposed taxon, supporting characters and unresolved alternatives.
- Which locust-forming taxon is proposed, and which observed characters distinguish it from local non-locust grasshoppers? definition
- Which identification key, expert determination or specimen comparison supports that identification? provenance
Observation subject
The boundary between an individual locust and evidence collected from a group or trace.
Individual evidence boundary
Identify whether evidence concerns a living individual, specimen, egg or unresolved group observation.
- Does this record concern one distinguishable animal or egg, a specimen, or an observation that cannot resolve individuals? boundary
- Which photograph, specimen identifier or tracking evidence allows later observations to be attributed to this same individual? provenance
Development and condition Developmental stage, reproductive evidence and physical capacity.
Eggs, hoppers and adults require different interpretation and support different actions.
Developmental status
Evidence of stage, moulting and reproductive development.
Stage and maturity
Record stage and maturity only to the resolution supported by species-specific observations.
- Which characters establish egg, hopper or adult status, and can a hopper instar be assigned reliably? measurement
- What direct evidence supports sex, reproductive maturity, recent moulting or egg-laying? measurement
Physical capacity
Observable condition affecting survival, movement and handling.
Locomotion and impairment
Separate stage-appropriate limitations from injury or unexplained impairment.
- What movement has been observed, and what wing or leg damage could constrain it? measurement
- Do inactivity or abnormal movements require repeat observation, specialist assessment or a change in handling? action
Phase and aggregation Phase-related evidence and the individual's relationship to nearby locusts.
Phase expression is central to locust assessment but must not be inferred from a single generic visual cue.
Phase expression
Taxon- and stage-specific interpretation of behavioural and morphological evidence.
Phase evidence profile
Retain separate observations and their timing before assigning a phase interpretation.
- Which behavioural, colour or morphological observations support a phase assessment for this taxon and stage? measurement
- Does the evidence justify a phase label, indicate transition, or leave phase unresolved? boundary
- What observation history documents crowding or isolation rather than merely assuming it from the present location? provenance
Collective association
Local density, coordinated movement and links to a separately modelled collective.
Band or swarm link
Record the evidence connecting this individual to a hopper band, swarm or other aggregation.
- What local density and coordinated walking or flight were observed, over what area and interval? measurement
- Which collective record should own group extent, abundance and direction, and what supports linking this individual to it? boundary
Feeding and habitat use Direct interactions with vegetation, ground conditions and immediate surroundings.
Presence alone does not demonstrate crop consumption, breeding or habitat suitability.
Feeding evidence
Observed consumption and its relationship to nearby plant damage.
Confirmed food use
Connect feeding observations to identified food and distinguish them from inferred damage attribution.
- Which plant or other material and which part were directly observed being consumed? measurement
- Is nearby damage attributable to this observed feeding, or does attribution require a separate crop or population assessment? boundary
Microhabitat and breeding
Immediate habitat use and evidence of reproduction at the observation site.
Site use evidence
Distinguish transit, resting, feeding and breeding using observed behaviour and site conditions.
- Where and when was the locust observed, and what substrate, vegetation and temperature accompanied its activity? measurement
- Was egg-laying or an associated egg pod observed, or is breeding-site use only suspected? boundary
Observation and intervention Decisions about identification, reporting, sampling, containment and referral for management.
An agent needs evidence-based next actions that respect identification uncertainty and the limits of an individual record.
Evidence acquisition
Choose the next observation or sample needed to resolve a consequential uncertainty.
Targeted identification and sampling
Match observation or collection methods to the missing diagnostic evidence.
- Which additional view, measurement or expert examination would resolve the most consequential uncertainty about taxon, stage or phase? action
- If capture or sampling is needed, what authorised protocol preserves diagnostic features and records collection context? action
Management decision interface
Connect the individual record to applicable reporting and management processes.
Justified response
Record the grounds for monitoring, reporting, containment or referral without prescribing a population treatment from one sighting.
- Given identification confidence, location and aggregation evidence, which applicable reporting or monitoring procedure should be followed? action
- What additional population evidence and local authority are required before a control decision can be made? boundary
- If the locust is held, what verified containment and disposition procedure applies to its taxon and collection location? action
What the second pass must settle
- Does the registry intend locust to cover all locust-forming grasshopper taxa, and which taxonomic authority should determine that coverage?
- Which validated phase indicators apply to each covered taxon and life stage, and how should conflicting behavioural and morphological evidence be represented?
- How should unresolved eggs and egg pods link to individual locust records without implying unsupported identification or individual continuity?
- Which neighbouring registry models own hopper bands, swarms and outbreaks, and what evidence is sufficient to establish membership?
- Which jurisdiction-specific reporting, collection, containment and management protocols must an agent consult before acting?
